The mean weight of a breed of yearling cattle is 1074 pounds. Suppose that weights of all such animals can be described by the Normal model N( 1074,85) a) How many standard deviations from the mean would a steer weighing 1000 pounds be? b) Which would be more unusual, a steer weighing 1000 pounds, or one weighing 1250 pounds? a) A steer weighing 1000 pounds is standard deviations below the mean. (Round to two decimal places as needed.)
