Agency leadership decides to use the vehicle weight data from its random sample of 750 vehicles to estimate the mean vehicle weight of all passenger vehicles currently on the road. Construct a 95% One-Sample T confidence interval for the mean vehicle weight of all passenger vehicles currently on the road. Assume that all necessary Central Limit Theorem conditions for a One-Sample T confidence interval have been met.

What is the 95% lower limit?

(Round to two decimal places as needed.)

Part 2

What is the 95% upper limit?

(Round to two decimal places as needed.)

Part 3

Using the 95% confidence interval, would it be plausible to conclude that the mean vehicle weight of all passenger vehicles currently on the road is 2500 pounds?

A. Yes, since 2500 lies outside the constructed confidence interval.

B. No, since 2500 lies within the constructed confidence interval.

C. No, since 2500 lies outside the constructed confidence interval.

D.Yes, since 2500 lies within the constructed confidence interval.

Part 4

Explain why the agency would construct a confidence interval instead of collecting vehicle weight information of all passenger vehicles currently on the road.
