Interpret the slope of the regression line in the context of the question: The slope has no practical meaning since people cannot read a negative number of books. As x goes up, y goes down. For every additional movie that people watch each year, there tends to be an average decrease of 0.98 books read. Interpret the y-intercept in the context of the question: The y-intercept has no practical meaning for this study. If someone watches 0 movies per year, then that person will read 8 books this year. The best prediction for a person who doesn't watch…
