Students investigated the packaging of potato chips. They purchased 6 randomly selected bags of chips marked with a net weight of 28.2 grams at different randomly selected stores. They carefully weighed the contents of each bag, recording the weights (in grams): 29.4, 28.6, 28.7, 28.8, 29.3, 28.7 a) Do these data satisfy the assumptions for inference? Explain. b) Find the mean and standard deviation of the weights. c) Test the hypothesis that the net weight is as claimed.
