Suppose that a particular airline’s passengers had a mean weight for their carry-on items of 16 pounds, the FAA standard average weight, before implementation of the checked-bag fee. The airline conducts a hypothesis test to determine whether the current mean weight of its passengers’ carry-on items is more than 16 pounds. It selects a random sample of 67 passengers and weighs their carry-on items. The sample mean is x̄ = 17.1 pounds, and the sample standard deviation is s = 6.0 pounds. The airline uses a significance level of α = 0.05 to conduct its hypothesis test.
