Answer to Question 1

In the F-test, we rejected H0 at  = 0.05, but failed to reject H0 under same level of significance in the Kruskal-Wallis test. The reason is that under the assumption of normality in the populations, nonparametric tests such as Kruskal-Wallis are less powerful than parametric tests, such as ANOVA.

Answer to Question 2

FALSE
