Problem 4E

The article “Hatching Distribution of Eggs Varying in Weight and Breeder Age” (S. Viera, J. Almeida, et al., Brazilian Journal of Poultry Science 2005: 73-78) presents the results of a study in which the weights of 296 eggs from 27 week-old breeding hens averaged 54.1 g with a standard deviation of 4.4 g, and weights of 296 eggs from 59 week-old hens averaged 72.7 g with a standard deviation of 4.7 g. Find a 95% confidence interval for the difference between the mean weights.
