Increasing the width of a confidence interval can be achieved by:
a) Increasing the confidence level: A higher confidence level requires a wider interval to capture the true population parameter with greater certainty.
b) Decreasing the number in the sample: A smaller sample size results in less precision and a wider confidence interval due to increased sampling variability.
c) Increasing the variance: A larger variance implies greater dispersion in the data, which requires a wider confidence interval to accommodate the increased uncertainty.

The fee should the companyfee should the company charge to maximize their revenue charge to maximize their revenue is $7.50.

To determine the fee that the online computer game company should charge to maximize their revenue, we need to calculate the revenue for each fee rate listed in the table below:

| Fee Rate | Number of Subscribers | Revenue |
|----------|----------------------|---------|
| $8.00    | 10,000               | $80,000 |
| $7.75    | 10,500               | $81,375 |
| $7.50    | 11,000               | $82,500 |
| $7.25    | 11,500               | $83,375 |
| $7.00    | 12,000               | $84,000 |
| $6.75    | 12,500               | $84,375 |
| $6.50    | 13,000               | $84,500 |
| $6.25    | 13,500               | $84,375 |
| $6.00    | 14,000               | $84,000 |

From the table, we can see that the revenue initially increases as the fee rate decreases, but then starts to decrease after $7.50. This is because although the number of subscribers increases with a lower fee rate, the decrease in revenue from each individual subscriber outweighs the increase in subscribers.

Therefore, the fee rate that would maximize revenue for the online computer game company is $7.50. This is the fee rate where the revenue is the highest, at $82,500. We know this is the optimal fee rate because any higher fee rate will result in fewer subscribers, and any lower fee rate will result in a decrease in revenue per subscriber.

If a local park is open for biking every 12 day open for paddling every 8 day and if today the park is open for both options, then the next date when the park will be open will be on the 24th day. So Hana should pick 24th day from today next.

Every 12 day the local park is open its path for biking and every 8 day they open their lake or paddling. That is in every multiple of 12 days the biking option is available and every multiple of 8 days the paddling option is available.

If today both the biking and paddling option are open, then the next day where both options will be open can be determined by calculating the least common multiple of 12 and 8.

12 = 2×2×3

8 = 2×2×2

LCM (12, 8) = 2×2×2×3

LCM(12, 8) = 24

LCM of 12 and 8 is 24. So 24 days from today, the park will be open for both options.

Question 1: A point estimate is the value of a statistic that estimates the value of a parameter.A point estimate is a single number that is used to estimate the value of an unknown parameter of a population, such as a population mean or proportion

Question 2: False

Mu (μ) is not used to estimate X. Mu represents the population mean, while X represents the sample mean. The sample mean, X, is used as an estimate of the population mean, μ.

Question 3: True

Beta (β) is indeed used to estimate the population proportion (p) when conducting hypothesis testing on a sample. Beta represents the probability of making a Type II error, which occurs when we fail to reject a null hypothesis that is actually false. By calculating the probability of a Type II error, we indirectly estimate the population proportion, p, under certain conditions and assumptions.

Step-by-step explanation:

The given function is:

                                                  C(p) = 0.95p

Where p represents the number of bolts purchased. We can calculate the cost based on the number of bolts purchased.

An important distinction between discrete and continuous data is that the continuous data is measured while discrete data is calculated or counted. Since we are obtaining the data by calculation, it must be discrete data.

The function can take on only specific values. For example for p=0, C is 0 and for p=1 the value of C is 0.95. The function cannot take any value in between 0 and 0.95. This is a characteristic of discrete function. A continuous function can take all possible values in an interval.  

Therefore, the answer to this question is: The Function models discrete data.

The relationship between the radius and volume of a cylinder with a height of 4 feet is nonlinear because the volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. In this case, the height is fixed at 4 feet. As we change the radius, the volume changes in a nonlinear manner.

The volume increases much faster as the radius increases. This can be seen from the exponential nature of the formula, as the radius is squared. Therefore, even a small increase in the radius results in a substantial increase in the volume, making the relationship between radius and volume nonlinear.

In contrast, if the height were to be proportional to the radius, then the relationship between radius and volume would be linear. This is because the volume would be proportional to the product of the radius and height, which is a linear relationship.

Therefore, the nonlinear relationship between radius and volume, in this case, is due to the exponential nature of the formula for the volume of a cylinder and the fixed height of 4 feet.

The weight of a randomly chosen American passenger car is assumed to be uniformly distributed between 1,568 pounds and 4,980 pounds. This means that any weight within this range is equally likely to be chosen.

In this scenario, the weight of a randomly chosen American passenger car is modeled as a uniformly distributed random variable. A uniform distribution is characterized by a constant probability density function within a specific range. In this case, the range is defined as 1,568 pounds to 4,980 pounds.

A uniform distribution implies that each weight within the given range has an equal probability of being selected. This means that a car weighing 1,568 pounds has the same likelihood of being chosen as a car weighing 4,980 pounds. The distribution is "uniform" because the probability is evenly spread across the entire range.

By assuming a uniformly distributed random variable for the weight of American passenger cars, we can make predictions and analyze various statistical properties. For example, we can calculate the probability of a car weighing within a certain range or estimate the average weight of randomly chosen cars. This assumption provides a simple and convenient model for understanding the weight distribution of American passenger cars in a probabilistic framework.

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given the equation x^2 = 2y.

The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:

To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].

Now we need to find the value of x that will minimize this expression.

We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.

Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T

he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given :

present value (P) = $20,000

interest rate (r) = 8%

compounding monthly (n) = 12

Time (t) = 10 years

To find : Future value after 10 years when interest monthly gets compounded

Now,

we know the formula is

future value = present value × (1 + interest rate)^years

                    = P × ( 1 + r / n )^ nt

inserting values in the given formula we get,

future value    = $20,000 × ( 1 + 8% / 12 )^ 10 × 12

                       =  $20,000 × ( 1 + 8 / 1200 )^ 120

                       =  $20,000 × (1 + 0.0066)^120

The result is approximately 0.839 or 83.9%.

In a newspaper report, it was mentioned that out of 2 million lie detector tests, an estimated 300,000 produced erroneous results. The probability of an erroneous result in these tests can be calculated using the given information. Let P (erroneous result) be the probability of an erroneous result in these tests.

P (erroneous result) = 300,000/2,000,000 = 0.15 Now we need to find the probability that at least one of the ten tests picked at random from these 2 million tests produced an erroneous result. Let P (at least one erroneous result in ten tests) be the probability of getting at least one erroneous result in ten tests.

P (at least one erroneous result in ten tests) = 1 - P (no erroneous result in ten tests)

P (no erroneous result in ten tests) = (1 - P (erroneous result))^10

P (no erroneous result in ten tests) = (1 - 0.15)^10

P (no erroneous result in ten tests) = 0.161

Therefore, P (at least one erroneous result in ten tests) = 1 - P (no erroneous result in ten tests)

P (at least one erroneous result in ten tests) = 1 - 0.161

P (at least one erroneous result in ten tests) = 0.839

the length of diagonal BD is approximately 11.49 feet.

Let's label the isosceles trapezoid as ABCD, where AB is the longer base and CD is the shorter base. We know that AB = 22 feet and the non-parallel sides (BC and AD) are each 7 feet long.

Since ABCD is an isosceles trapezoid, we know that the base angles (the angles formed by the longer base and each of the non-parallel sides) are congruent. Let's label each of these angles as x.

We also know that the sum of the base angles of a trapezoid is 360°. Since ABCD is an isosceles trapezoid with two congruent base angles and a sum of 140°, we can set up an equation:

2x + 140° = 360°

Subtracting 140° from both sides, we get:

2x = 220°

Dividing by 2, we get:

x = 110°

So each base angle of ABCD measures 110°.

Now we can use the law of cosines to find the length of the diagonal BD. Let's label the intersection of the diagonals as point E, and the length of BD as d. Then we have:

d^2 = 7^2 + 7^2 - 2(7)(7)cos(110°)

Simplifying, we get:

d^2 = 98 - 98cos(110°)

Using a calculator, we find that cos(110°) is approximately -0.34202. Substituting this value, we get:

d^2 = 98 - 98(-0.34202)

Simplifying, we get:

d^2 ≈ 131.88

Taking the square root of both sides, we get:

The probability of a student doing well on an exam given that they spend time reading is approximately 0.983 or 98.3%.

To calculate the probability of a student doing well on an exam given that the student spends time reading, we need to use conditional probability.

Let's denote:

P(R) as the probability of a student spending time reading (P(R) = 0.59),

P(E) as the probability of a student doing well on an exam (P(E)),

P(E|R) as the probability of a student doing well on an exam given that they spend time reading (P(E|R) = 0.58).

The formula for conditional probability is:

P(E|R) = P(E and R) / P(R).

Given that P(E and R) = 0.58 (the probability of a student doing well on an exam and spending time reading) and P(R) = 0.59 (the probability of a student spending time reading), we can substitute these values into the formula:

P(E|R) = 0.58 / 0.59 = 0.983.

Therefore, the probability of a student doing well on an exam given that the student spends time reading is approximately 0.983 or 98.3%.

To calculate the covariance matrix and the correlation matrix, we need to arrange the covariances and standard deviations in a matrix form.

Let's denote the covariance matrix as C and the correlation matrix as R.

The covariance matrix C is given by:

C = [cov(x1, x1) cov(x1, x2) cov(x1, x3)]

[cov(x2, x1) cov(x2, x2) cov(x2, x3)]

[cov(x3, x1) cov(x3, x2) cov(x3, x3)]

The correlation matrix R is calculated by dividing each covariance by the product of the corresponding standard deviations:

R = [cov(x1, x1)/(σ1 * σ1) cov(x1, x2)/(σ1 * σ2) cov(x1, x3)/(σ1 * σ3)]

[cov(x2, x1)/(σ2 * σ1) cov(x2, x2)/(σ2 * σ2) cov(x2, x3)/(σ2 * σ3)]

[cov(x3, x1)/(σ3 * σ1) cov(x3, x2)/(σ3 * σ2) cov(x3, x3)/(σ3 * σ3)]

Now, let's substitute the given values into the formulas:

C = [cov(x1, x1) cov(x1, x2) cov(x1, x3)]

[cov(x2, x1) cov(x2, x2) cov(x2, x3)]

[2 1 cov(x3, x3)]

R = [cov(x1, x1)/(σ1 * σ1) cov(x1, x2)/(σ1 * σ2) cov(x1, x3)/(σ1 * σ3)]

[cov(x2, x1)/(σ2 * σ1) cov(x2, x2)/(σ2 * σ2) cov(x2, x3)/(σ2 * σ3)]

[cov(x3, x1)/(σ3 * σ1) cov(x3, x2)/(σ3 * σ2) cov(x3, x3)/(σ3 * σ3)]

R = [cov(x1, x1)/(3 * 3) cov(x1, x2)/(3 * 2) cov(x1, x3)/(3 * 2)]

[cov(x2, x1)/(2 * 3) cov(x2, x2)/(2 * 2) cov(x2, x3)/(2 * 2)]

[cov(x3, x1)/(2 * 3) cov(x3, x2)/(2 * 2) cov(x3, x3)/(2 * 2)]

Simplifying further:

C = [cov(x1, x1) 3 2]

[3 cov(x2, x2) 1]

[2 1 cov(x3, x3)]

R = [cov(x1, x1)/9 cov(x1, x2)/6 cov(x1, x3)/6]

[cov(x2, x1)/6 cov(x2, x2)/4 cov(x2, x3)/4]

[cov(x3, x1)/6 cov(x3, x2)/4 cov(x3, x3)/4]

Now, let's substitute the given covariance values into the matrices:

C = [cov(x1, x1) 3 2]

[3 cov(x2, x2) 1]

[2 1 cov(x3, x3)]

R = [cov(x1, x1)/9 cov(x1, x2)/6 cov(x1, x3)/6]

[cov(x2, x1)/6 cov(x2, x2)/4 cov(x2, x3)/4]

[cov(x3, x1)/6 cov(x3, x2)/4 cov(x3, x3)/4]

We don't have the exact values for cov(x1, x1), cov(x2, x2), and cov(x3, x3), so we cannot calculate the specific covariance matrix and correlation matrix. However, you can substitute the respective covariance values to obtain the final matrices.

Top Triangle

Let the base angles of the top triangle = y

y + 102 = 180

y = 78

The vertex

Is found by adding the two base angles together and subtract that from 180

y + y + vertex = 180

78 + 78 + vertex = 180

156 + vertex = 180

vertex = 180 - 156

vertex = 24 degrees

Bottom Triangle

Because the base angles are connected by a vertically opposite angle on the bottom triangle, both base angles are 26

Therefore 26 + 26 + x = 180

52 + x = 180

x = 180 - 52

x = 128
