1. Work the 0.01 significance level. Use STATISTIX to build your ANOVA.
2. Suppose that first observation for each type of tire is made using one particular kind of automobile, the second observation is made using a second particular kind, and so on. Determine at the 0.05 significance level whether there is a difference (a) between the types of tires and (b) between the kinds of automobiles. Use SAS to build your ANOVA.
3. Use MINITAB to work the 0.01 level of significance.
4. Suppose that first entry for each teaching method corresponds to a student at one particular school, the second method corresponds to a student at another school, and so on. Test the hypothesis at the 0.05 significance level that there is a difference
(a) between the teaching methods and
(b) between the schools. Use STATISTIX to build your ANOVA.
