As a commercial buyer for a private supermarket brand, suppose you take a random sample of 12No. 303 cans of green beans at a canning plant. The net weight of the drained beans in each can is reported in Table 8.8. Determine (a) the mean net weight of string beans being packed in each can for this sample and (b) the sample standard deviation. (c) Assuming that the net weights per can are normally distributed, estimate the mean weight per can of beans being packed using a 95 percent confidence interval.
