A corporation that maintains a large fleet of company cars for the use of its sales staff is interested in the mean distance driven monthly per sales person. The following table gives the monthly distances in miles driven by a random sample of sales persons:

17 sales persons: 2522, 2535, 2305, 1946, 2185, 2219, 1873, 1936, 1951, 512, 2086, 2444, 2214, 1881, 2231, 1855, 2525

Based on this sample, find a 95% confidence interval for the mean number of miles driven monthly by members of the sales staff, assuming that monthly driving distances are normally distributed.

Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.

What is the lower limit of the confidence interval?
What is the upper limit of the confidence interval?
