Bob is interested in examining the relationship between the number of bedrooms in a home and its selling price. After downloading a valid data set from the internet, he calculates the correlation. The correlation value he calculates is only 0.05What does Bob conclude? A)Bob gives up on his research becauser=.05 means there is no relationship of any kind between bedrooms and selling price. B) Bob continues his research because even though there is no linear relationship here, there could be a different relationship.
Answers
Bob continues his research because even though there is no linear equation relationship between the number of bedrooms and selling price, there could be another type of relationship.
Bob continues his research because even though the correlation value he calculated between the number of bedrooms and the selling price was only 0.05, this does not necessarily mean that there is no relationship of any kind between these two variables. It simply means that there is no linear relationship between the two. There could still be other types of relationships between the two variables, such as an exponential or quadratic relationship. It is possible that further analysis and exploration of the data set would reveal such a relationship and allow Bob to uncover the relationship between the two variables. Additionally, even if the correlation value is low, it does not necessarily mean that there is no relationship between the two variables. It simply means that the relationship is weak. Therefore, Bob should continue his research in order to uncover any potential relationships between the number of bedrooms and selling price.

Use the figure to write the segment addition postulate, write and equation and solve for x.
Pls explain
Answers
Answer:
\( x = 3 \)
Step-by-step explanation:
From the figure given, we have points A,B, and C, that are collinear. Therefore, according to the segment addition postulate, \( AB + BC = AC \).
We are given that:
AB = 9x + 7
BC = -5x + 20
AC = 39
An equation that can be used to solve for x would be:
\( (9x + 7) + (-5x + 20) = 39 \)
Solve for x
\( 9x + 7 - 5x + 20 = 39 \)
\( 9x - 5x + 7 + 20 = 39 \)
\( 4x + 27 = 39 \)
Subtract 27 from both sides
\( 4x + 27 -27 = 39 - 27 \)
\( 4x = 12 \)
Divide both sides by 4
\( \frac{4x}{4} = \frac{12}{4} \)
\( x = 3 \)

(a) how many paths are there from the point (0, 0) to the point (110, 111) in the plane such that each step either consists of going one unit up or one unit to the right? (b) how many paths are there from (0,0) to (210, 211), where each step consists of going one unit up or one unit to the right, and the path has to go through (110, 111)?
Answers
(a) The number of pathways in the plane from point (0, 0) to point (110, 111) when each step consists of walking one unit up or one unit to the right is known as the number of ways to go to a point in a grid using just right and up moves.
This is a classic combinatorial problem known as a binomial coefficient. The binomial coefficient C(110+111, 110) = C(221, 110) = 221!/(110!111!) is the number of ways to travel from (0, 0) to (110, 111).
(b) The number of paths from (0, 0) to (210, 111) where each step consists of walking one unit up or one unit to the right and the path must pass through (110, 111) is the product of two binomial coefficients.
First, as calculated in section 1, the number of pathways from (0, 0) to (110, 111) is C(110+111, 110) = C(221, 110). Second, there are C(210+211, 210) ways to get from (110, 111) to (210, 111). (210, 211). (421, 210). C(221, 110) * C is the total number of paths found by multiplying these two binomial coefficients (421, 210).

if you use significance level 0.1, what is closest to the probability of a type i error for your test?
Answers
When using a significance level of 0.1, the probability of making a Type I error is closely associated with that level. In this case, the probability of committing a Type I error, which means incorrectly rejecting a true null hypothesis, is 10% or 0.1.
When conducting a hypothesis test, the significance level is the probability of rejecting the null hypothesis when it is actually true. In other words, it is the probability of making a type I error.
If the significance level is set at 0.1, this means that the probability of making a type I error is 0.1 or 10%. Therefore, there is a 10% chance of rejecting the null hypothesis when it is actually true.It is important to note that the significance level is usually set prior to conducting the hypothesis test and is based on the researcher's preference for the trade-off between type I and type II errors. A lower significance level will decrease the probability of making a type I error but increase the probability of making a type II error, while a higher significance level will have the opposite effect.In summary, if you use a significance level of 0.1, the closest probability of making a type I error for your test is 0.1 or 10%.Know more about the significance level

The sum of two integers is 75. One of the numbers is three more than the other. What is the larger integer?
Answers
Step-by-step explanation:
Assign variables to the integers
Let the larger integer be 'A' and the smaller 'b'
Write Equations based on the Question
Since the sum of the integers is 75, then A + b = 75 (eq
1)
Since the larger number is three times more than the smaller, then A = 3b (eq2)
Combine the Equations and solve for variables
By substituting the value of A in eq1 into eq2
⇒ 3b + b = 75
4b = 75
b = ⁷⁵/₄ = 18.25
By substituting the value of b into eq1
⇒ A = 3(⁷⁵/₄)
A = ²²⁵/₄ = 56.25
∴ the larger integer is 56.25Check our Answer:
A + b = 56.25 + 18.75 = 75
39 is the answer
If $x$ is the larger integer, then the smaller integer is $x-3$. We find the sum and set it equal to 75:$$x+x-3=75\qquad\Rightarrow \qquad 2x=78\qquad\Rightarrow \qquad x=39$$The larger integer is $\boxed{39}$.

Answers
a) The sample mean years to maturity for corporate bonds = 16.9625
and the sample standard deviation = 8.2232
b) A 95% confidence interval for the population mean years to maturity: (14.4141, 19.5112)
c) The sample mean yield on corporate bonds is 4.5405
and the sample standard deviation = 2.3082
d) A 95% confidence interval for the population mean yield on corporate bonds: (3.825, 5.256)
a) The mean of the sample would be,
\(\bar{x}\) = (10.25 + 28 + 23 + 13.25 + 3, 7.5 + 26.5 + 21.25 + 3.25, 19 + 9.25 + 28.75 + 1.75 + 17 + 8.75 + 24 + 24.5 + 18+ 11.75 + 22 + 22.75 + 27.75 + 16.75 + 12 + 16.5 + 23.75 + 25.25 + 25.75 + 22.5 + 1.25 + 19.5 + 12.5 + 27.25 + 19.5 + 17.75 + 11.5+ 3.5 + 20 + 25.25 + 6.75) / 40
\(\bar{x}\) = 678.5 / 40
\(\bar{x}\) = 16.9625
And the sample standard deviation would be,
s = √(67.6203)
s = 8.2232
b)
We know that the formula for the confidence interval is,
CI = \(\bar{x}\) ± (z × s/√n)
Here, n = 40, \(\bar{x}\) = 16.9625, s = 8.2232 and z = 1.9600
Using above formula the 95% confidence interval for the population mean years to maturity would be,
CI = 16.9625 ± (1.9600 × 8.2232/√40)
CI = (16.9625 ± 2.548)
CI = (16.9625 - 2.548, 16.9625 + 2.548)
CI = (14.4141, 19.5112)
c) Consider sample yield on corporate bonds.
The mean would be,
\(\bar{x}\) = 181.62 / 40
\(\bar{x}\) = 4.5405
And the standard deviation would be,
s = √(5.327594)
s = 2.3082
d) Now we construct a 95% confience interval.
Here, n = 40, s = 2.3082, \(\bar{x}\) = 4.4505, and z = 1.9600
Using above formula the 95% confidence interval for the population mean years to maturity would be,
CI = 4.4505 ± (1.9600 × 2.3082/√40)
CI = (4.5405 ± 0.716)
CI = (4.5405 - 0.716, 4.5405 + 0.716)
CI = (3.825, 5.256)

The price of each ticket is given as follows:
Senior: $14.Student: $14.How to obtain the prices?The prices for each type of ticket are obtained via a system of equations, for which the variables are given as follows:
Variable x: price of a senior ticket.Variable y: price of a student ticket.On the first day of ticket sales the school sold 12 senior citizen tickets and 6 student tickets for a total of $252, hence:
12x + 6y = 252
2x + y = 42 (simplifying by 6).
y = 42 - 2x.
The school took in $98 on the second day by selling 6 senior citizen tickets and 1 student ticket, hence:
6x + y = 98
y = 98 - 6x.
Equaling the two equations, the value of x is obtained as follows:
42 - 2x = 98 - 6x
4x = 56
x = 56/4

d. It would be somewhat unusual if the sample mean were greater than 620.
e. It would not be unusual for an individual to get a score greater than 620, since the probability is relatively high (about 54%).
(a) To find the probability that the sample mean score is less than 589, we need to calculate the z-score and then use a normal distribution table or calculator to find the corresponding probability. The z-score is calculated as:
z = (x - μ) / (σ / √n) = (589 - 605) / (136 / √76) = -1.69
Using a normal distribution table or calculator, the probability corresponding to a z-score of -1.69 is 0.0455.
(b) To find the probability that the sample mean score is between 575 and 610, we need to calculate the z-scores for both values and then use a normal distribution table or calculator to find the area between them. The z-scores are:
z1 = (x1 - μ) / (σ / √n) = (575 - 605) / (136 / √76) = -2.21
z2 = (x2- μ) / (σ / √n) = (610 - 605) / (136 / √76) = 0.61
Using a normal distribution table or calculator, the probability corresponding to a z-score of -2.21 is 0.0138, and the probability corresponding to a z-score of 0.61 is 0.2714. Therefore, the probability that the sample mean score is between 575 and 610 is approximately 0.2714 - 0.0138 = 0.2576.
(c) To find the 85th percentile of the sample mean, we need to find the z-score that corresponds to an area of 0.85 to the left of it. Using a normal distribution table or calculator, we can find that the z-score is approximately 1.44. Therefore, the 85th percentile of the sample mean is:
x = μ + z(σ / √n) = 605 + 1.44(136 / √76) ≈ 620.65
(d) To determine whether it would be unusual if the sample mean were greater than 620, we need to find the corresponding probability. The z-score is calculated as:
z = (x - μ) / (σ / √n) = (620 - 605) / (136 / √76) ≈ 1.33
Using a normal distribution table or calculator, the probability corresponding to a z-score of 1.33 is approximately 0.0918. Therefore, it would be somewhat unusual (but not extremely rare) if the sample mean were greater than 620.
(e) To determine whether it would be unusual for an individual to get a score greater than 620, we need to convert the score to a z-score and then find the corresponding probability. Assuming that the variable is normally distributed, the z-score is calculated as:
z = (x - μ) / σ = (620 - 605) / 136 ≈ 0.11
Using a normal distribution table or calculator, the probability corresponding to a z-score of 0.11 is approximately 0.5440. Therefore, it would not be unusual for an individual to get a score greater than 620, since the probability is relatively high (about 54%).

Answers
The "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number.
When there are two middle numbers we average them.
We have:
3.9, 7, 3.3, 1, 1.4, 1.7, 2.1, 3.3, 5.2
Let's sort the numbers from the smallest to the largest
1, 1.4, 1.7, 2.1, 3.3, 3.3, 3.9, 5.2, 7
The median is 3.3Answer:
3.3
Step-by-step explanation:
The first thing you have to do is put them in order from least to greatest.
1, 1.4, 1.7, 2.1, 3.3, 3.3, 3.9, 5.2, 7
Check off one from the left side and one from the right side until you are left with the one in the middle.
When you do that, you are left with 3.3

what is the probability that washing dishes tonight will take me between 15 and 16 minutes? give your answer accurate to two decimal places.
Answers
The probability of washing dishes by me tonight will take between 15 and 16 minutes is 14.29%.
The term "uniform distribution" refers to a type of probability distribution in which the likelihood of each potential result is equal.
Let's consider, the lower limit for this distribution as a and the upper limit for this distribution as b.
The following formula gives the likelihood that we will discover a value for X between c and d,
\(P(c\leq X\leq d)=\frac{d-c}{b-a}\)
Given the time it takes me to wash the dishes is 11 minutes and 18 minutes. From this, a = 11 and b = 18.
Then,
\(P(15\leq X\leq 16)=\frac{16-15}{18-11}=0.1429=14.29\%\)
The answer is 14.29%.
The complete question is -
The time it takes me to wash the dishes is uniformly distributed between 11 minutes and 18 minutes. What is the probability that washing dishes tonight will take me between 15 and 16 minutes?
