Suppose an ANOVA has been performed on a completely randomized design containing six treatment levels. The mean for group 3 is 15.85, and the sample size for group 3 is eight. The mean for group 6 is 17.21, and the sample size for group 6 is seven. MSE is .3352.The total number of observations is 46. Compute the significant difference for the means of these two groups by using the Tukey-Kramer procedure. Let α = .05.
Answer to relevant QuestionsUsing the results of problem 11.5, compute a critical value by using the Tukey-Kramer procedure for groups 1 and 2. Use α = .05 Determine whether there is a significant difference between these two groups.Use Tukey’s HSD test to compute multiple comparisons for the data in problem 11.12. Let α = .01. State which regions, if any, are significantly different from other regions in mean starting salaryfigures?A randomized block design has a treatment variable with four levels and a blocking variable with seven blocks. Using this information and α = .01 complete the following table and reach a conclusion about the nullhypothesis.Suppose the following data have been gathered from a study with a two-way factorial design. Use α = .05 and a two-way ANOVA to analyze the data. State yourconclusions.Analyze the following data, gathered from a randomized block design using α = .05. If there is a significant difference in the treatment effects, use Tukey’s HSD test to do multiplecomparisons.
