1. The following data give the per capita consumption of milk in the years from 1983 to 1987. The data are from the U.S. Department of Agriculture, Food Consumption, Prices, and Expenditures, annual Year 1983 1984 Amount (in gallons per capita) 26.3 262 1986 1987 26.3 25.9 Find the sample mean and the sample variance of this set. You are given these data sets: A: 66, 68, 71, 72, 72, 75 B 2, 5, 9, 10, 10, 16 (a) Which one appears to have the larger sample variance? (b) Determine the sample variance of data set A. (c) Determine the sample variance of data set B. 3. The Masters Golf Tournament and the U.S. Open are the two m prestigious golf tournaments in the United Stat DECISIS you course, whereas the U.S. Open is played on different courses in different years. As a result, one might expect the sample variance of the winning scores in the U.S. Open to be higher than that of the winning scores in the Masters. To check whether this is so, we have collected the winning scores in both tournaments for 1981 to 1990.
