Question: The board member who originally wanted you to include only low income households in the survey is still concerned about the particular effect of the experimental curriculum on schools in low income neighborhoods. TO find the answer to this, you need to run a multiple regression model.

a) Create a dummy variable for the experimental curriculum and an interaction variable that interacts the experimental dummy and the income variable.
b) Estimate a multiple regression model that includes the curriculum dummy, income, and interaction variable as independent variables.
c) Calculate predicted values for the chgtestscores variable for both the new and old curriculum for income levels of $15,000, $30,000, $60,000, and $120,000.
d) Summarize and interpret the results of this model. What do you tell the board member about the effect of the new curriculum across different income levels?
