WHY DOES NO ONE REPLY TO MY Q"S!!!!!!

In 1940 the average size of a U.S. farm was 174 acres. Let's say that the standard deviation was 57 acres. Suppose we randomly survey 41 farmers from 1940.

Answer 1

117 is the smaller value and 231 is the larger value

Explanation:

Standard deviation is 57

Middle 50% is average and one standard deviation to each direction

So if the average is 174

174 - 57 is 117

174 + 57 is 231
