Students investigating the packaging of potato chips purchased 6 bags of chips marked with a net weight of 28.1 grams. They carefully weighed the contents of each bag, recording the following weights (in grams): 29.2, 28.1, 29.2, 28.6, 28.7, 28.7. Complete parts a through c below. a) Do these data satisfy the assumptions for inference? Explain. b) Find the mean and standard deviation of the weights. (round to two decimal places) c) Create a 95% confidence interval for the mean weight of such bags of chips. (round to one decimal place)
