a. Use technology to make a scatterplot using Rotten Tomatoes as the independent variable and Metacritic as the dependent variable. Based on your scatterplot, do you think there is a strong linear association between these variables?

b. Compute the correlation coefficient, $r$, and write the equation of the regression line. Use the words “Rotten Tomatoes” and “Metacritic” in your equation. Round to two decimal places.

c. Provide an interpretation of the slope of the regression line.

d. Provide an interpretation of the y-intercept of the regression line or explain why it would not be appropriate to do so.
