*. The mean difference is significant at the 0.05 level.

Answer 1

The null and alternative hypotheses are: Ho:ui= u2 = u3 Hy: Not all the means are equal. The value of test statistic is: F = 7.708 The p-value = 0.000 Conclusion: The p-value of F test is less than 0.05. Hence we reject the null hypothesis at 0.05 level of significance and conclude that there is significant difference in mean age of who they voted for in the 1992 Presidential Election (Clinton vs. Bush vs. Perot). i.e. The age is related to who they voted for in the 1992 Presidential Election (Clinton vs. Bush vs. Perot). The mean age who they voted for Perot is significantly lower than the whom they voted for Clinton and Bush.
