If you haven’t already done Problem 6 on 2006–2007 movies, do it now. The scatter plots of Total US Gross versus 7-day Gross or 14-day Gross indicate some possible outliers at the right—the movies that did great during their first week or two. Identify these outliers (you can decide how many qualify) and move them out of the data set. Then redo Problem 6 without the outliers. Comment on whether you get very different results. Specifically, do these outliers affect the slope of either regression line? Do they affect the standard error of estimate or R2?
