The example in this section used the Flesch Reading Ease scores for randomly selected pages from books by Tom Clancy, J. K. Rowling, and Leo Tolstoy. When the Flesch-Kincaid Grade Level scores are used instead, the analysis of variance results from STATDISK are as shown in Figure 10.2. Assume that we want to use a 0.05 significance level in testing the null hypothesis that the three authors have Flesch-Kincaid Grade Level scores with the same mean.

a. What is the null hypothesis?

b. What is the alternative hypothesis?

c. Identify the P-value.

d. Based on the preceding results, what do you conclude about equality of the population means?
