Math 143 – ANOVA Analysis of Variance (ANOVA) 1 Recall‚ when we wanted to compare two population means‚ we used the 2-sample t procedures . Now let’s expand this to compare k ≥ 3 population means. As with the t-test‚ we can graphically get an idea of what is going on by looking at side-by-side boxplots. (See Example 12.3‚ p. 748‚ along with Figure 12.3‚ p. 749.) 1 Basic ANOVA concepts 1.1 The Setting Generally‚ we are considering a quantitative response variable as it relates to one or

positive association between the size of the home and the selling price? Use the .05 significance level. Step 1: Step 2: The alternative hypothesis is which indicates a one tail test. The degrees of freedom (df) = n-2=12-2=10. The t value at the significance level of .05 and df of 8 and from appendix F is 1.812. The decision rule is to reject the null hypothesis because the test statistic is greater then 1.812. Step 3: According to Appendix F‚ we can assume that P 1.744)‚ there is
