Use the data in HollywoodMovies2011 to use revenue from a movie’s opening weekend (OpeningWeekend) to predict total world gross revenues by the end of the year (WorldGross). Both variables are in millions of dollars.

(a) Use technology to create a scatterplot for this relationship. Describe the scatterplot: Is there a linear trend? How strong is it? Is it positive or negative? Does it look like revenue from a movie’s opening weekend is a good predictor of its future total earnings?

(b) The scatterplot contains an outlier in the top right corner. Use the dataset to identify this movie.

(c) Use technology to find the correlation between these variables.

(d) Use technology to find the regression line.

(e) Use the regression line to predict world gross revenues for a movie that makes 50 million dollars in its opening weekend.
