Haven’t you always wanted to own a Porsche? We investigated the Boxster (their cheapest model) and performed an online search at www.cars .com on December 30, 2012. Asking prices were well beyond our meager professorial salaries, so instead we focused on odometer readings (mileage). Here are reported readings for a sample of 16 Box sters:

A normal quantile plot supports the assumption that mileage is at least approximately normally distributed. The R software reports the following summary statistics for this data:

a. Estimate true average mileage in a way that conveys information about precision and reliability.
b. Predict the mileage for a single Porsche Boxster in a way that conveys information about precision and reliability. How does the prediction compare to the estimate calculated in part (a)?
