d. 7² = e. Interpret ²: O Given any fixed number of movies watched per year, 76% of the population reads the predicted number of books per year. (Round to two decimal places) O There is a 76% chance that the regression line will be a good predictor for the number of books people read based on the number of movies they watch each year. There is a large variation in the number books people read each year, but if you only look at people who watch a fixed number of movies each year, this variation on average is reduced by 76%. O 76% of all people watch about the same number of movies as they read books each year. f. The equation of the linear regression line is: ŷ= + x (Please show your answers to two decimal places) g. Use the model to predict the number of books read per year for someone who watches 4 movies per year. Books per year = (Please round your answer to the nearest whole number.) h. Interpret the slope of the regression line in the context of the question: O The slope has no practical meaning since people cannot read a negative number of books. O As x goes up, y goes down. O For every additional movie that people watch each year, there tends to be an average decrease of 1.77 books read. i. Interpret the y-intercept in the context of the question: O The average number of books read per year is predicted to be 11 books. The best prediction for a person who doesn't watch any movies is that they will read 11 books each year. O If someone watches 0 movies per year, then that person will read 11 books this year. The y-intercept has no practical meaning for this study.
