A tourist agency in Hawaii advertises that the mean daily cost of meals and lodging for a family of 4 traveling in Hawaii is $650. You work for a consumer protection advocate and want to test whether it is more expensive than this. In a random sample of 45 families of 4 traveling in Hawaii, the mean daily cost of meals and lodging is $657. Assume that the population is normally distributed and that previous studies have shown that the population standard deviation is o = $40. At a = 0.05, do you have enough evidence to reject the tourist agency's advertised price?
