In 1940 the average size of a U. S. farm was 174 acres. Let's say that the standard deviation was 54 acres. Suppose we randomly survey 44 farmers from 1940. Part (a)
In words, define the random variable X.
a. the number of U. S. farms
b. the number of acres of a U. S. farm
c. the number of animals on a U. S. farm
d. the number of square feet of a U. S. farm

Part (b)
In words, define the random variable
a. the average number of animals on a U. S. farm
b. the average number of acres of a farm in the sample of 44 farmers
c. the average number of farms in each state in the United States
d. the average number of square feet of a farm in the sample of 44 farmers

Part (c)
Give the distribution of X. (Round your standard deviation to two decimal places.
X~ ( · )

Part (d)
The middle 50% of the distribution for X, the bounds of which form the distance represented by the IQR, lies between what two values? (Round your answers to two decimal places.)
acres (smaller value)
acres (larger value)
