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 37 farmers from 1940. O Part (a) In words, define the random variable X. the number of acres of a U.S. farm the number of square feet of a U.S. farm the number of animals on a U.S. farm O the number of U.S. farms O Part (b) In words, define the random variable X. the average number of square feet of a farm in the sample of 37 farmers the average number of acres of a farm in the sample of 37 farmers O the average number of farms in each state in the United States the average number of animals on a U.S. farm O Part (c) Give the distribution of X. (Round your standard deviation to two decimal places.)
