    Question

    Suppose dummy coding is used in a regression to determine if two lesson programs, program A (ProgAProg_{A}) and program B (ProgBProg_{B}), are statistically significantly better than a current program, program C (ProgCProg_{C}). The regression equation is: Y’=55+(6*ProgA)–(4*ProgB)Y’ = 55+(6*Prog_{A})–(4*Prog_{B}). What is the mean score of the current programCprogram_{C}?
