The weights of 4 randomly and independently selected bags of potatoes labelled 20 pounds were found to be 21, 21.5, 20.5, 21.2 pounds. Assume Normality. Find a 95% confidence interval for the mean weight of all bags of potatoes. Does the interval capture 20 pounds? 1. Sample size is 2. Interpret the interval: We are 95% confident that the mean weight of all bags of potatoes is between Ib. and Ib. Round to 1 decimal. 3. Is it reasonable that the bags of potatoes are labelled 20 pounds? (yes/no)
