In Example 8.5 on page 500 we find evidence from the ANOVA of a difference in mean pulse rate among students depending on their award preference. The ANOVA table and summary statistics for pulse rates in each group are shown below.

Use this information and/or the data in StudentSurvey to compare mean pulse rates, based on the ANOVA, between each of three possible pairs of groups:
(a) Academy Award vs Nobel Prize.
(b) Academy Award vs Olympic gold medal.
(c) Nobel Prize vs Olympic gold medal.
