Perform a multiple-range test to determine the nature of the differences among the three detergents in Example 15.1. Use the 0.01 level of significance.
Answer to relevant QuestionsPerform a multiple-range test to determine the nature of the block differences in Example 15.2. Use the 0.05 level of significance. Perform appropriate multiple- range tests, using the 0.05 level of significance, to characterize the differences among the bonder means and the operator means found in Exercise 15.29. Estimate the values of any main effects found to be significant in Exercise 15.42. Show that if a one-way analysis of variance is per-formed on the ranks of the observations instead of the observations themselves, it becomes equivalent to a test based on the H statistic. Rework Exercise 16.18 using the signed- rank test based on Table X. In exercise The following are the amounts of money (in dollars) spent by 16 persons at an amusement park: 20.15, 19.85, 23.75, 18.63, 21.09, 25.63, 16.65, ...
