Textbook cost is one expense that university students often complain about. Does the size of the book (measured by the number of pages) relate to the price of the book n dollars)? Use the Fitted Line plot provided on Moodle to answer the following questions; do not do any unnecessary calculations. Question 2 [MOODLE QUESTIONS 13 to 17] Fitted Line Plot Price = - 3.42 + 0.1473 Pages 180 S 29.7605 R-5q 67.7%% 160 R-Sqladj) 66.5% 140 120 100 Price 80 60 40 20 200 400 600 800 1000 1200 PagesBased on the scatterplot, what can you say about the relationship between size and price of a book? Explain. 1 A v B I E E State the regression equation. 1 AY B I IEUse the regression equation to find the predicted price, y, for observation 4 (a book with 400 pages). Answer: Calculate the residual for observation 4 (the book with 400 pages and cost $128.50) Answer: Which of the following is the correct interpretation for the slope, in the context of the problem. Select one: O a. >As the size of the book increases by 1 percent, the predicted price increases by 0.1473 percent. O b. As the size of the book increases by 0.1473 page, the predicted price increases by $1. O c. As the size of the book increases by 1 page, the average price of the book increases by $0.1473. O d. As the size of the book increases by 1 page, the predicted price increases by $0.1473
