Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm
and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard
deviation of 6.9 eggs. Which of the following is the 90% confidence interval for the true mean number of eggs
chickens from this poultry farm lay in one month?
