We are operating a small upscale local restaurant. To determine our brand strength, we wish to estimate from how far away our customers have come to dine with us. We randomly sample 36 customers and find that they have come an average distance of 10.4 miles. The sample standard deviation is 4.26 miles. Compute by hand a 95% confidence interval for the mean traveling distance of our diners. Confirm your result with Minitab. Considering closely what the interval estimates, what other information might we want about the driving distances?
