Solved: Agreeableness, gender, and wages. Refer to the
Chapter 12, Problem 131E(choose chapter or problem)
Agreeableness, gender, and wages. Refer to the Journal Of Personality and Social Psychology (Feb. 2012) study of on-the-job agreeableness and wages, Exercise 12.107(p. 730). Recall that the researchers modeled mean income,E(y), as a function of both agreeableness score (x1) and a dummy variable for gender (x2 = 1 if male, 0 if female).Use the data saved in the file to analyze the residuals of the model,
\(E(y)=\beta_0+\beta_1 x_1+\beta_2\left(x_1\right)^2+\beta_3 x_2\)
What model modifications, if any, do you recommend?
