Answer to Problem 27E

The weight below 984 considered to be unusually low for such an animal.

Explanation of Solution

Given:

  $\mu$ = 1152

  $\sigma$ = 84

In general, the weight to be considered unusual if that weight below $\mu -2\sigma$ .

Therefore, $\mu -2\sigma =1152-2\times 84=984$

Hence, the weight below 984 considered to be unusually low for such an animal.
