Question

Comparing three or more means by using ANOVA (1) Identify the null hypothesis & alternative hypothesis, (2) Identify Significance Level, (3) calculate test-statistic, (4) sketch correct graph shape and LABEL test-statistic and p-value completely, (5) determine whether to reject or fail-to-reject the null hypothesis, and (6) write a final conclusion that addresses the original claim. 5) (14 points) A researcher wishes to determine whether there is a difference in the average age of middle school, high school, and college teachers. Teachers are randomly selected. Their ages are recorded below. Test the hypothesis that there is no difference in the average age of each group. Use ? = 0.01.
