Textbook Question

Chapter 12.8, Problem 12.87ACB

Reality TV and cosmetic surgery. Refer to the Body Image: An International Journal of Research (March 201 0) study of the impact of reality TV shows on a college student’s decision to undergo cosmetic surgery, Exercise 12.43 (p. 715). The data saved in the file were used to fit the interaction model, E(y) = β₀ + β₀x₁ + β₂x₄ + β₃x₁x₄, where y = desire to have cosmetic surgery (25-point scale), x₁ = {1 if male, 0 if female}, and x₄ = impression of reality TV (7-point scale). From the SPSS printout (p. 715), the est1mated equation is:

y ^ = 11.78 − 1.97 x 1 + .58 x 4 − .55 x 1 x 4

a. Give an estimate of the change in desire (y) for every 1-point increase in impression of reality TV show (x₄) for female students.
b. Repeat part a for male students.
