Find the test statistic Find critical value Is there sufficient evidence to conclude that there is a difference in the mean rating of the pens following exposure to five advertisements? Is there significant evidence that Ad A and Ad B differ in mean ratings? Is there significant evidence that Ad A and Ad C differ in mean ratings? Is there significant evidence that Ad A and Ad D differ in mean ratings? Is there significant evidence that Ad A and Ad E differ in mean ratings? Is there significant evidence that Ad B and Ad C differ in mean ratings? Is there significant evidence that Ad B and Ad D differ in mean ratings? Is there significant evidence that Ad B and Ad E differ in mean ratings? Is there significant evidence that Ad C and Ad D differ in mean ratings? Is there significant evidence that Ad C and Ad E differ in mean ratings? Is there significant evidence that Ad D and Ad E differ in mean ratings? At the 0.01 level of significance, is there evidence of a difference in the variation in ratings among the five advertisements? Determine the hypothesis. Determine test statistic and critical value for that. Determine if there is sufficient evidence for that. Which ad should you use and why?

Extracted text: An experiment is designed to compare five different advertisements for a pen. Advertisement A greatly undersells the pen. Advertisement B slightly undersells the pen. Advertisement C slightly oversells the pen. Advertisement D greatly oversells the pen. Advertisement E correctly states the pen. A sample of 30 adult respondents is randomly assigned to the five advertisements. After reading the advertisement, all respondents unknowingly receive the same pen to evaluate and are then asked to rate the pen from 1 to 7 (lowest to highest) on three characteristics. The combined scores of three ratings for the 30 respondents are in the data table. Complete parts (a) through (d) below. : Click on the icon to view the data table.
