Sullivan Statistics Survey: Age and Politics Do peoples political philosophy tend to change with age? One technique we may use to answer this question is to see if the mean age of conservatives, moderates, and liberals differ. Load the results of the survey into a statistical spreadsheet and treat the results as a random sample of adult Americans. (a) State the null and alternative hypotheses. (b) Verify that the requirements to use the one-way ANOVA procedure are satisfied. Normal probability plots indicate that the sample data come from normal populations. (c) Are the mean ages for the three political philosophies different at the a = 0.1 level of significance? (d) Draw boxplots of the ages of the three political philosophies to support the analytic results obtained in part (c).
