Statistics students in Oxnard College sampled 10 textbooks in the Condor bookstore and recorded the number of pages in each textbook and its cost. The bivariate data are shown below: Number of Pages (xx) Cost(yy) 517 57.04 396 45.52 680 73.6 661 78.32 300 36 266 38.92 661 76.32 612 76.44 267 33.04 434 58.08 A student calculates a linear model yy =  xx + .
