1. The Myers Summer Casual Store tells its customers that a special order will take six weeks (42 days). During the recent months, the owner has received several complaints that the special orders are taking longer than 42 days. A sample of 12 special orders delivered in the last month showed that the mean waiting time was 51 days, with a standard deviation of eight days.
