Mr. S has an appetite for a certain brand of potato chips, which are typically packaged in 14oz bags. However, Mr. S has come to suspect that the net weight of the chips in each bag is significantly less than the advertised 14oz. He takes a sample of 16 bags of chips and finds the mean to be 13.82oz with a standard deviation of 0.24oz. Assuming the weights are normally distributed, what should he conclude?
