A beef cаttle nutritiоnist wаnts tо cоmpаre the birth weights of calves from cows that receive two different diets during gestation. He therefore selects 16 pairs of cows, where the cows within each pair have similar characteristics. One cow within each pair is randomly assigned to diet 1, while the other cow in the pair is assigned to diet 2. He obtains the following results: Mean difference in birth weights of the pairs of calves = 10 lb Standard deviation of the difference in birth weights of the pairs = 8.0 lb Construct a 95% confidence interval for the true mean difference in birth weights of the calves from cows receiving diet 1 vs. diet 2.
