One group of 15 students studies the text of a story about gang violence while listening to rap music. A second group of 10 students studies the same story while listening to classical music.

8. (9 points). The actual levels of the 4 design factors are as follows: A (10, 20), B (5,7), C (50, 100) and D (20, 30).  Suppose that the experimenter selects a model with the terms A, D, and the AD interaction. The predicted response from this model when these factors are at levels A = 16, D = 26 is
