Statistics

Students investigated the packaging of potato chips. They purchased 6 randomly selected bags of chips marked with a net weight of 28.3 grams at different randomly selected stores. They carefully weighed the contents of each bag, recording the weights below (in grams). 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. HA: H#28.3 The test statistic is t= (Round to two decimal places as needed.)a) Do these data satisfy the assumptions for inference?
