1. A 2D data set S has the following averages and SDs. Average SD 100 x-coordinate 4 y-coordinate 450 20 The correlation coefficient is r = 0.8. The scatter diagram of the data set S is football-shaped. Let L be the regression line to estimate y from x. a. Find the r.m.s. of the regression line L. b. Estimate the y-coordinate of a point in the data set S whose x-coordinate is T = 108. How likely is this estimate to be off?
