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 list gives the monthly distances in miles driven by a random sample of 17 sales persons. 2611, 2131, 2148, 2682, 2261, 2344, 2609, 2064, 1936, 2569, 2273, 1964, 2164, 2588, 2428, 2346, 2224 Send data to calculator Based on this sample, find a 90% 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 find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: Il X ? Upper limit
