s 24-25 are based on the regression model developed in this question, lets call it Regression3. Comparing predictors using correlations is not ideal as it presumes the predictors operate independently. This is seldom the case. Therefore, it is best to draw comparisons by including predictors in a single model. Toward this end, we will run a multiple regression model using Adverts and AirPlay as predictors of Sales. Lets call this Regression3. Examine the output. What is the unstandardized regression coefficient for AirPlay
