The U. S. Department of Transportation provides the number of miles that residents of the 75 largest metropolitan areas travel per day in a car. Independent simple random samples for both Buffalo and Boston are located in the Excel Online file below. Construct a spreadsheet to answer the following questions. A B
1 Buffalo Boston
2 26 21
3 27 14
4 39 11
5 23 19

Required:
a. What is the point estimate of the difference between the mean number of miles that Buffalo residents travel per day and the mean number of miles that Boston residents travel per day?
b. What is the 95% confidence interval for the difference between the two population means?

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
