A herd of 1,500 steer gains an average of 5.00 pounds of weight every month. The standard deviation for the population weigh gain is 7.1 pounds. Assume that the herd has a normal distribution of weight and of weight gain. A cattle herder decides to increase the herd’s weight by feeding them a special high‐protein grain for a month. The herder predicts that his herd has gained more weight because of this food. He then selects 30 steers, weighs them...
