In baseball, is there a linear correlation between batting average and home run percentage? Let x represent the batting average of a professional baseball player, and let y represent the player's home run percentage (number of home runs per 100 times at bat). A random sample of n = 7 professional baseball players gave the following information. x 0.245 0.253 0.286 0.263 0.268 0.339 0.299 y 1.5 3.9 5.5 3.8 3.5 7.3 5.0 Use a calculator to verify that Σx = 1.953, Σx2 = 0.551, Σy = 30.5, Σy2 = 152.69 and Σxy = 8.834.
