16-) The data for a random sample of six paired observations are shown in the next table. Pair Sample 1 Sample 2 1 7 4 2 3 1 3 7 4 6 2 5 4 4 6 8 7 a) Calculate the difference between each pair of observations by subtracting observation 2 from observation 1. Use the differences to calculate d. b) If #, and #2 are the means of populations 1 and 2, respectively, express ud. c) Form a 95% confidence interval for a. (Use s= = 2) d) Test the null hypothesis Ho: Ha = 0 against the alternative hypothesis Ho: Ha # 0. Use a = 0.05
