at your cereal: Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 16 boxes. It is reasonable to assume hat the population is approximately normal. 14.09 13.96 14.18 14.19 14.17 14.04 14.17 13.96 14.07 14.06 14.13 14.14 14.18 14.16 14.11 14.10 Send data to Excel Part: 0 / 2 Part 1 of 2 Construct a 99.5% confidence interval for the mean weight. Round the answers to three decimal places.

Given the data set below find the following; 45, 34, 65, 20, 15, 25 a. Compute the sample mean b. Compute the sample standard deviation c. Compute the standard error of the mean.

Eat your cereal: Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 12 boxes. It is reasonable to assume that the population is approximately normal. 13.03 14.98 13.12 13.13 13.11 13.03 13.16 14.98 13.06 13.05 13.12 13.13 The quality control manager is concerned that the mean weight is actually less than 14 ounces. Based on the confidence interval, is there a reason to be concerned? Explain.
