An article presents the results of a study in which the weights of 295 eggs from 27 week-old breeding hens averaged 54.1 g with a standard deviation of 4.4 g, and weights of 295 eggs from 59 week-old hens averaged 72.7 g with a standard deviation of 4.7 g. Let μXμX represent the population mean weight for 59-week-old hens and let μYμY represent the population mean weight for 27-week-old hens. Find a 95% confidence interval for the difference μX−μYμX−μY .
