Question

Samples of pages were randomly selected from three different novels. The Flesch Reading Ease scores were obtained from each page, and the TI-83/84 Plus calculator results from analysis of viance are given below. Use a 0.05 significance level to test the claim that the three books have the same mean Flesch Reading Ease score. Click the icon to view the TI-83/84 Plus calculator results. Click the ioon to view the TI-83/84 Plus calculator results. What is the conclusion for this hypothesis test? O A. Fail to reject Ho. There is insufficient evidence to warrant the rejection of the claim that the three books have the same mean Flesch Reading Ease score O B. Fail to reject Ho. There is sufficient evidence to warrant the rejection of the claim that the three books have the same mean Flesch Reading Ease score. O c Reject Ho There is insufficient evidence to warrant the rejection of the claim that the three books have the same mean Flesch Reading Ease score. OD. Reject Ho-There is sufficient evidence to warrant rejection of the claim that the three books have the same mean Flesch Reading Ease score. Click to select your answer.

Explanation / Answer

The null hypothesis states that the population means are all equal.

From F table with df1 = 2 and df2 = 34 we found:

Critical F value = 3.276

An F statistic is a value you get when you run an ANOVA test or a regression analysis to find out if the means between two populations are significantly different.

A small p-value (typically 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.

Here, F>Fcritical thus also, we reject null so, means not equal.

D option is the answer.
