In Problem 14.4 you used views and number of ingredients to predict the number of times recipes were saved in users' online recipe books (stored in Chicken). Using the results from that problem, compute the coefficient of partial determination, \(r_{Y 1.2}^{2}\) and \(r_{Y 2.1}^{2}\), and interpret their meaning.

Problem 14.4

The popularity of a websites dedicated to food and cooking depends on the number of people who visit them and consume the content they host. The file Chicken contains data on 40 chicken-based main course recipes posted at one such website, measuring each recipe's popularity by the number of views, the number of times it was saved in users' online recipe books, and the number of ingredients it needs (to determine whether it is easy or complicated).
