Interpret the ANOVA tests and address the following:

• An ANOVA tests the extent to which the variances of the means in more than two groups are different (1 = 2 = 3).
• The F-ratio is calculated by Excel's output (Between Groups / Within Groups) and is displayed in the "F" column.
• You can determine if there are equal variances among the group means by stating whether the generated F > F crit, in which case you can reject the null hypothesis.
