90% + or F distribution. 1. Consider a study with a balanced completely randomized design with 5 treatments and a total of 30 experimental units. Suppose that a one-factor ANOVA model with fixed effects is appropriate for analyzing these data. a. The following is a partial analysis of variance table. Complete the table to test for the significance of the treatment effects. Use R to compute the p-value. source df SS MS F p-value Treatment 84.655 7.0866 Error Hint: Think in terms of the relationship between df, SS, MS, and F. b. Give the conclusion of the F-test for the equality of means at a = 5%. c. From the above table give an estimate of the variance of the random error i.e. o', and compute the coefficient of determination R2 and the observed value of Cohen's f. d. Suppose that we have observed the group means y1 = 9.315 and y2 = 8.202. Give 95% confidence interval for /1 - /2
