5 Food Production At a time whenenergy conservation is so important, some scientiststhink closer scrutiny should be given to the cost(in energy) of producing various forms of food. Supposeyou wish to compare the mean amount of oilrequired to produce 1 acre of corn versus 1 acre ofcauliflower. The readings (in barrels of oil per acre),based on 20-acre plots, seven for each crop, are shownin the table.Corn Cauliflower5.6 15.97.1 13.44.5 17.66.0 16.87.9 15.84.8 16.35.7 17.1a. Use these data to find a 90% confidence intervalfor the difference between the mean amounts of oilrequired to produce these two crops.b. Based on the interval in part a, is there evidence ofa difference in the average amount of oil requiredto produce these two crops? Explain.
