A tourist agency in Kansas claims the mean daily cost of meals and lodging for a family of four traveling in the state is $201. You work for a consumer protection advocate and want to test whether the cost differs from $201. In a random sample of 35 families of four traveling in Kansas, the mean daily cost of meals and lodging is $216. Assume that from previous research, the population standard deviation is known to be σ = 30. Do you have enough evidence to reject the agency’s claim? Use α = 0.05.
