The average wait time to get seated at a popular restaurant in the city on a Friday night is 15 minutes. Is the mean wait time different for men who wear a tie? Wait times for 15 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 13, 13, 14, 13, 17, 16, 17, 17, 13, 14, 15, 14, 16, 15, 14 What can be concluded at the the a = 0.10 level of significance level of significance? a.
