The study mentioned in Exercise 5 also included measurement of the outside diameters of the 16 bushings. Two of the students measured each of the bushings, with the results given here. Bushing 1 2 3 4 Student A .3690 .3690 .3690 .3700 Student B .3690 .3695 .3695 .3695 Bushing 5 6 7 8Student A .3695 .3700 .3695 .3690 Student B .3695 .3700 .3700 .3690Brushing 9 10 11 12 Student A .3690 .3695 .3690 .3690 Student B .3700 .3690 .3695 .3695 Bushing 13 14 15 16 Student A .3695 .3700 .3690 .3690Student B .3690 .3695 .3690 .3690(a) If you want to compare the two students average measurements, the methods of formulas (6.35), (6.36) and (6.38) are not appropriate. Why? (b) Make a 95% two-sided confidence interval for the mean difference in outside diameter measurements for the two students.
