Textbook Question
Chapter 9.3, Problem 13E
Refer to Exercise 12. The treatments with a delivery ratio of 1:0 were controls, or blanks. It was discovered after the experiment that the high apparent levels of sorption in these controls was largely due to volatility of the trifluralin. Eliminate the control treatments from the data.
- a. Estimate all main effects and interactions.
- b. Construct an ANOVA table. You may give
ranges for the P-values. - c. Is the additive model plausible? Provide the value of the test statistic, its null distribution, and the P-value.
- d. Construct an interaction plot. Explain how the plot illustrates the degree to which interactions are present.

The director of marketing at Vanguard Corporation believes that sales of the company's Bright Side laundry detergent (S) are related to Vanguard's own advertising expenditures (A), as well as the combined advertising expenditures of its three biggest rival detergents (R).The marketing director collects 36 weekly observations on S, A, and R . Vanguard's marketing director is comfortable using parameter estimates that are statistically significant at the 10 percent level or better. Give the specific statistical tool that can be used to this problem.
