The mean weight of a breed of yearling cattle is 1104 pounds. Suppose that weights of all such animals can be described by a Normal model with a standard deviation of 58 pounds. What weight would be considered unusually low for such an animal?
Select the correct choice below and fill in the answer boxes within your choice.
A. Any weight more than 2 standard deviations below the mean, or less than _____________ pounds, is unusually low. One would expect to see a steer 3 standard deviations below the mean, or less than _______________ pounds only rarely.
B. Any weight more than 3 standard deviations below the mean, or less than ___________ pounds, is unusually low. One would expect to see a steer 2 standard deviations below the mean, or less than ___________ pounds only rarely.
C. Any weight more than 1 standard deviations below the mean, or less than ________ pounds, is unusually low. One would expect to see a steer 2 standard deviations below the mean, or less than _____________ pounds only rarely.
