    Question

    Suppose dummy coding is applied in a regression to determine whether math program A (Math_A) and math program B (Math_B) perform statistically significantly better than math program C. The estimated regression equation is: Y’=55+(6*MathA)–(4*MathB)Y’ = 55+(6*Math_A)–(4*Math_B). What is the average score of math program C?
