Students investigating the packaging of tortila chips purchased 6 bags of chips marked with a not weight of 280 grams. They carefully weighed the contents of each bag, recording the following weights on arams) 29 4 28 1 202 288, 289 288 Complete carts a through d below a) Do these data satisfy the assumptions for interence? Explain OA. The Randomization Condition is met The histogram is extremely skewed night, so the Nearly Normal Condition is not met OB. The Randomization Condition is met The histogram is bimodal and not symmetric, so the Nearly Normal Condition is s met OC. The Randomization Condition is not met and cannot be assumed to be true. The histogram is unimodal and roughly symmetric, so the Nearly Normal Condition is met OD The Randomization Condition may not be satisfied However, it is reasonable to think that these bags are representative of all bags of chips. The histogram is unimodal and roughly symmetric, so the Nearly Normal Condition is met b) Find the mean and standard deviation of the weights ya grams S grams (Round to two decemal places as needed) c) Create a 95% confidence interval for the mean weight of such bags of chips GOD grams (Round to one decimal place as needed) d) Explain in context what your interval means Select the correct choice below OA The interval contains the true mean weight of the contents of a bag of tortita chips 95% of the time OB. We are 95% confident that the interval contains the true mean weight of the contents of a bag of tortila chips OC. 95% of all bags of tortilla chips will have a mean weight that falls within the interval OB 95% of the weights of the bags of tortilla chips will be contained in the interval
