Chapter 5, Problem 4(choose chapter or problem)
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.
