Pt 3

5. A website has visitors list the books they've read and rate books. Books can also be tagged with keywords such as "vampires" or "mystery" to describe the contents. For a sample of 15 books each, the mean ratings for three different tags ("dinosaurs", "pirates", and "vampires") are found to be 4.2, 3.93, 4.08. An ANOVA table for the data set is shown below. Source df SS MS F p-value Treatment 2 0.5747778 0.2873889 2.920713 0.0649 Error 42 4.132666 0.09839682 Total 44 4.7074447 Determine if, at alpha = 0.05, this data provides evidence that the mean rating is different across these three tags. Remember to show all parts of the hypothesis test you use and use the computer output given (null and alternative, p-value, decision, interpretation)
