You work at Yellowstone where there are 350 wolves running around in the park. Your boss wants to know how they are doing, so he assigns you to catch 100 of these wolves and make a confidence interval for the mean weight of all wolves in the park. You catch the 100 and find that their mean weight is 120 pounds with a standard deviation of 15 pounds. Make a 98% Cl for the mean weight of all wolves in Yellowstone.
