Table 2.5 (page 109) gives data on the true calories in 10 foods and the average guesses made by a large group of people. Exercise 2.26 explored the influence of two outlying observations on the correlation. (a) Make a scatterplot suitable for predicting guessed calories from true calories. Circle the points for spaghetti and snack cake on your plot. These points lie outside the linear pattern of the other 8 points. (b) Find the least-squares regression line of guessed calories...
