The weights in pounds of a breed of yearling cattle follows the
Normal model
N(1128,62).
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
nothing
pounds, is unusually low. One would expect to see a steer 3
