Julia calculates the performance index using the indicators as building blocks. However, during the games, the performance index was computed based on other criteria. Test whether the multiple regression model is still significant for both the Red and Blue teams at a 1% level of significance. Note: The independent variables remain the seven indicators, but the dependent variable is now the performance index during the games.
