The Jordeen Bottling Company recently did an extensive sampling of its soft-drink inventory in which 5,000 cans were sampled. Employees weighed each can and used these weights to determine the fluid ounces in the cans. The data are in a file called Jordeen. Based on this sample data, should the company conclude that the mean volume is 12 ounces? Base your conclusion on a 95% confidence interval estimate and discuss.
