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.
