In Exercises 1–4, use the Flesch-Kincaid Grade Level measurements from randomly selected pages in Tom Clancy’s

The Bear and the Dragon, J. K. Rowling’s Harry Potter and the Sorcerer’s Stone, and Leo Tolstoy’s War and Peace. Those measurements reflect the reading level of the sampled text.

1. ANOVA
Use a 0.05 significance level with analysis of variance to test the claim that the three books have the same mean Flesch-Kincaid Grade Level. Do the three books appear to be written with the same reading level?

2. Kruskal-Wallis Test
Use a 0.05 significance level with the Kruskal-Wallis test to test the claim that the samples of Flesch-Kincaid Grade Level measurements are from books with the same median reading level.

3. t Test
Use a 0.05 significance level with a t test to test the claim that the samples of Flesch- Kincaid Grade Level scores from Clancy and Rowling have the same mean.

4. Wilcoxon Rank-Sum Test
Use a 0.05 significance level with the Wilcoxon rank-sum test to test the claim that the samples of Flesch-Kincaid Grade Level scores from Clancy and Rowling are from populations having the same median.
