To determine if the bolts vary by more than the required variance, we can conduct a hypothesis test. The null hypothesis (H₀) states that the variance of the bolts is equal to or less than the required variance (σ² ≤ 0.025), while the alternative hypothesis (H₁) states that the variance is greater than the required variance (σ² > 0.025).

Next, we need to determine the critical value(s) of the test statistic. Since we are testing for variance, we will use the chi-square distribution. For a one-tailed test with α = 0.01 and 14 degrees of freedom (n-1), the critical value is 27.488.

Now, we can compare the test statistic to the critical value. The test statistic is calculated as (n-1) * s² / σ², where n is the sample size (15), s² is the sample variance (0.1587²), and σ² is the required variance (0.025).

If the test statistic is greater than the critical value, we reject the null hypothesis and conclude that the bolts vary by more than the required variance. Otherwise, we fail to reject the null hypothesis.

Answer:

7.393691004

Step-by-step explanation:

7.4 is the standard deviation from the following set of observation 20, 25, 30, 36, 32, 43​

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The given data set is 20, 25, 30, 36, 32, 43​

Firstly we have to find the mean

Mean=20+25+30+36+32+43/6

=186/6

=31

The deviations from the mean are 20-31=-11

25-31=-6

30-31=-1

36-31=5

32-31=1

43-31=12

Using the definition of standard deviation (σ) , we have:

σ=√121+36+1+25+1+144/6

σ=√328/6

σ=√54.66=7.4

Hence, 7.4 is the standard deviation from the following set of observation 20, 25, 30, 36, 32, 43​

Step-by-step explanation:

I assume the function is

f(x) = 2x³ - kx² + x - 8k

With 98% confidence interval, all teenagers' mean number of hours watching TV per week will be (26.6,29.4).

98% confidence interval can be calculated as

Point estimate± Error margin

Point estimate=mean number of hours watching TV

students=28.

Error margin=1.4.

As per given data, the 98% confidence interval for all teenagers is

=28± 1.4

=(28-1.4,28+1.4)

=(26.6,29.4)

Statisticians use confidence intervals to assess the level of uncertainty in a sample variable. For instance, a researcher may select numerous samples at random from the same population and compute a confidence interval for each sample to estimate how each sample may correctly reflect the true value of the population variable. With certain intervals including the true population parameter and others not, each produced dataset is distinct. Confidence intervals are a set of values that are constrained by the mean of the statistic and are likely to include an unidentified population parameter. The confidence level is the proportion of likelihood, or certainty, that, after multiple draws from a random sample, the confidence interval would contain the true population parameter.

Answer:

1 yard = 3 feet

We will need to multiply the yard lengths by 3 to convert the measurements to feet.

8 feet x 3 = 24 yards  >>>> 8 ft = 24 yards

6 feet x 3 = 18 yards  >>>> 6 ft = 18 yards

5 feet x 3 = 15 yards  >>>> 5 ft = 15 yards

Then you would do Length x width x depth x 7.5 (Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.)

The volume of the rectangular prism is V = 504 m³

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Let the volume of the prism be represented as V

Now , the value of V is

Let the height of the rectangular prism be H = 9 m

Answer:

(0,-5)

Step-by-step explanation:

The null hypothesis would not be rejected and the researcher would fail to find statistical significance at the chosen alpha level of .05.

If a researcher sets the alpha level at .05 and obtains a p-value of .06, it means that the p-value is greater than the chosen significance level. The alpha level, also known as the significance level, represents the threshold for determining whether the results are statistically significant or not.

In hypothesis testing, the null hypothesis assumes that there is no significant difference or relationship between variables.

If the p-value is less than or equal to the alpha level, it suggests that there is enough evidence to reject the null hypothesis and conclude that there is a significant difference or relationship.

However, if the p-value is greater than the alpha level, as in this case with a p-value of .06, it means that the observed data does not provide sufficient evidence to reject the null hypothesis.

Answer:

\(y=-\frac{3}{2}x-2\)

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: \(\frac{y2-y1}{x2-x1}\)

Given points: (0, -2), (-4, 4)

(0, -2) = (x1, y1)

(-4, 4) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the slope formula:

\(\frac{4-(-2)}{-4-0}\)

Simplify:

4 - (-2) = 4 + 2 = 6

-4 - 0 = -4

\(\frac{6}{-4}=-\frac{3}{2}\)

The slope is \(-\frac{3}{2}\).

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, -2)) into the equation and solve for b:

\(-2 = -\frac{3}{2}(0)+b\)

-2 = 0 + b

-2 = b

The y-intercept is -2.

Now that we know the slope and the y-intercept, we can write the equation:

\(y=-\frac{3}{2}x-2\)

The probability that the height of a randomly chosen child is between 44.75 and 58.35 inches is approximately 0.8830.

To solve this problem, we need to find the area under the normal curve between the two given heights.

We can use the standard normal distribution by converting the given values into z-scores. The formula for calculating a z-score is

z = (x - μ) / σ

where x is the value we want to convert, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

For the lower bound of 44.75 inches

z1 = (44.75 - 53.3) / 4.3 = -1.98

For the upper bound of 58.35 inches

z2 = (58.35 - 53.3) / 4.3 = 1.17

Now, we need to find the area under the normal curve between these two z-scores. We can use a standard normal table or a calculator to find this probability.

Using a standard normal table, the probability of z being between -1.98 and 1.17 is approximately 0.8830.

Step-by-step explanation:

Answer:

We can use the Pythagorean theorem to solve this:

The Pythagorean theorem states that the hypotenuse of a triangle (the longest side), squared is equal to the sum of the other 2 sides of the triangle, squared. It can be expressed as so:

c^2=a^2+b^2 where c represents the hypotenuse; a and b represent the other 2 sides.

Now that we have an equation we can solve:

c^2=8^2+8^2

c^2=64+64

c^2=128

Since there is no perfect square for 128 we need to put in in simplest radical form

c=√128

Find a number that has a perfect square and multiplies by another number to equal 128

c=√64 x 2

This can be rewritten as so:

c=√64√2

Now for the last step find another perfect square for 64 and have it outside the square like so:

c=8√2

There is no perfect square for 8 so this is in simplest radical form

what is the problem ? you teacher gave you even the conversion rates in the question.

so, when 1 gallon = 3.79 liters, then how much is 4 gallons ?

4 gallons is 4 times 1 gallon. so, of course, we need to apply the same factor to the other side too.

4 gallons = 4×3.79 = 15.16 ≈ 15 liters

and e do the same for all the other table elements :

8 liters = 8×0.26 = 2.08 ≈ 2 gallons

12.5 liters = 12.5×0.26 = 3.25 ≈ 3 gallons

To find the unit rate that compares the length of the couch in the dollhouse to the length of the couch in the real living room, we need to convert the measurements to the same unit of measurement. Let's convert the length of the couch in the real living room from feet to centimeters:

1 foot = 30.48 centimeters

So, the length of the couch in the real living room is:

8 feet x 30.48 centimeters/foot = 243.84 centimeters

Now we can calculate the unit rate:

Unit rate = length of couch in dollhouse / length of couch in real living room

Unit rate = 6 centimeters / 243.84 centimeters

Unit rate = 0.0246

Therefore, the unit rate that compares the length of the couch in the living room to the length of the couch in the dollhouse is 0.0246 cm/cm.
