For the data in Exercise 16.1, a. Calculate treatment effects and show that the regression model reproduces these treatment effects. b. Demonstrate that for the regression model is equal to for the analysis of variance.

Taking the data from Exercise 16.1, add the scores 5 and 8 to the Average group and the scores 2, 3, 3, and 5 to the Good group. Rerun the analysis for Exercise 16.1 using the more complete data.
