- A box office analyst seeks to predict opening weekend box office gross for movies. Toward this goal, the analyst plans to use online trailer views as a predictor. For each of the 66 movies, the number of online trailer views from the release of the trailer through the Saturday before a movie opens and the opening weekend box office gross (in millions of dollars) are collected and stored in the accompanying table. Assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1. Interpret the meaning of the slope, b1, in this problem. Predict the mean opening weekend box office gross for a movie that had 80 million online trailer views. What insights can be obtained about predicting opening weekend box office gross from online trailer views?6. another retail merchant who sells face masks spent a total $55 for advertising its product. using the regression model in (4), predict the sale of this merchant.The least-squares regression equation is y=784.6x+12,431 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region.

In a large study of 18,125 doctors representing multiple hospitals in the United States, the fitted regression line is: (# Malpractice suits) = 2-0.1 x (years of work) The r2=0.36 for this regression. How do you interpret the r2 value? Assuming it is statistically significant, what is the interpretation of the coefficient for “years of work”? If a doctor has worked for 10 years, what is their predicted number of malpractice suits?
