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 18 sales persons:
2315, 1862, 2690, 2286, 2545.2355.2373.2328, 2449. 2455, 2074, 1853,2149,2038. 2243, 2671, 2369, 2405
Based on this sample, find a 99% confidence interval for the mean number of miles driven monthly by members of the sales staff, assuming that monthly
driving distances are normally distributed. Then complete the table below.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
What is the lower limit of the confidence interval?
What is the upper limit of the confidence interval?
