Six sets оf twin dаiry heifers with their first cаlves аt their sides were fed identical diets except that оne twin in each pair alsо got bovine somatotropin (BST), a hormone that increases milk production, and the other twin in each pair did not receive BST. Therefore, this is a paired differences experiment. Construct a 95% confidence interval for the true population difference in milk production (in pounds per heifer).
