(Hint: Use inverse normal calculator.) The Virginia Cooperative Extension reports that the mean weight of yearling Angus steers is 1152 pounds. Suppose that weights of all such animals can be described by a normal model with a standard deviation of 84 pounds. What is the cutoff value for the highest 10% of steer weights? for the lowest 20% of steer weights? for the middle 40% of steer weights (two cutoffs)?
