In a random sample of ​people, the mean driving distance to work was miles and the standard deviation was miles. Assume the popu

lation is normally distributed and use the​ t-distribution to find the margin of error and construct a ​% confidence interval for the population mean . Interpret the results. Identify the margin of error. nothing ▼ square miles miles per hour miles ​(Round to one decimal place as​ needed.) Construct a ​% confidence interval for the population mean. ​(Round to one decimal place as​ needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. nothing​% of all random samples of people from the population will have a mean driving distance to work​ (in miles) that is between the​ interval's endpoints. B. It can be said that nothing​% of the population has a driving distance to work​ (in miles) that is between the​ interval's endpoints. C. With nothing​% ​confidence, it can be said that most driving distances to work​ (in miles) in the population are between the​ interval's endpoints. D. With nothing​% ​confidence, it can be said that the population mean driving distance to work​ (in miles) is between the​ interval's endpoints.

Answer:

D. With 99​% ​confidence, it can be said that the population mean driving distance to work​ (in miles) is between the​ interval's endpoints

Step-by-step explanation:

The new confidence interval is narrower than the confidence interval for the t-distribution and the center is 21.7

please note that the options chosen are different for the attachment and the question here but are same answer

The figure below is a regular octagon with a side length of 8 inches.
Masteriza [31]

Answer:

309in²

Step-by-step explanation:

Area of an octagon is expressed as;

A=2(1+√2)a²

a is the side length of the octagon

Given

a = 8

Substitute into the formula

A = 2(1+√2)(8)²

A = 2(1+√2)(64)

Expand

A = 2(64+64√2)

A = 128+128√2

A = 128+128(1.414)

A = 128+181.01

A = 309in²

Hence the area of the octagon is 309in²
