- Run a multiple regression where the dependent variable is ratings and the independent variables are star and fact. CBC Management has several questions:
- Executives wish to know how much being fact-based or having one star contributes to a movies rating. What can you tell them about this?
- Are either, both, or neither of the independent variables significantly related to the ratings at 95% confidence? Justify your answers referring to the relevant figures.
- C. How well does this regression analysis explain the ratings? Should the executives count on the results from this analysis? Justify your answers referring to the relevant figures.
