What % of variation in Gross revenue is NOT explained by your final regression model (Q1.4 in the problem set)

(Based on the final regression model in Q1.5 of the problem set) Keeping everything else the same, increase in number of dislikes on social media results in increase in gross revenue.

Based on the final regression model in Q1.5 of the problem set, what is the error (error in prediction = actual value – predicted value) in your prediction for the The Lego Movie (Movie # 28 in the dataset)? 

Based on the final regression model in Q1.4 of the problem set, social media dislikes has [impact] impact on gross revenue.

The following problems are based on Problem Set: Question 1.4 Run a regression analysis to predict gross revenue based on ratings, and the various conventional and social media metrics. Your final model should have the best predictive power (% of variation explained) AND where all regression slopes are significant at 10% or less.

[percentile] % of the diamond sold by Tiffany & Co in 2017 weigh 1.04 carats or less.

If two diamonds have the same physical dimensions (except length) and quality of cut, and one diamond is 1 mm longer than the other, then the longer one will, on average, have a $______ lower price.

Problem Set: Question 1.5:  Some studio executives believe that the effects of budget (a conventional metric) and likes (a social media metric) on gross revenue depend on whether the movie is sequel or not. Run a regression analysis to predict gross revenue based on ratings, and the various conventional and social media metrics, and any new variable needed to capture the executives’ beliefs as stated above. Your final model should have the best predictive power (% of variation explained) AND where all regression slopes are significant at 10% or less.

We are 95% confident that if two diamonds have the same physical dimensions and weight, a diamond with ‘premium’ quality of cut, will have a higher price by $1381.34 to $1537.52 than a diamond with [cut] quality of cut.
