2.2. (6 points) Ms. Chen points out that it also might matter what platform people play on: their game can be played on four different video game consoles: PS3, PS4, XBOX360, and XBOX One. These values are contained in the variable Platform. Run an analysis to see how Platform and Game_Type explain Duration. Recall that she believed that people will play longer in multi- vs. single-player games, so be sure to specifically address that. (Hint: what is/are the appropriate test(s)? Can you rely on "muggle" managers to ask questions "correctly"?) Ans) On running a regression analysis with Duration as the dependent variable and Platform and Game_Type as the independent variables, only the Game_Type and Intercept have statistically significant estimates. The duration of multi-player games is around 944 seconds more than the single-player games. However, The R-squared value is 0.02993, suggesting that only approximately 3% of the variation in Duration is explained by Game Type and Platform combined
