Problem 8 (10 points) The Farm Bureau collects data to estimate the wheat yield per acre for farms in the county. They take a random sample of 35 wheat fields in the county and find the mean yield is 33.4 bushels per acre. Assume the standard deviation for all fields is 2.7 bushels per acre. (b) With the same confidence level and standard deviation, what would the sample size need to be to estimate the mean yield to within plus or minus 0.5 bushels per acre?
