Assume that the U.S Open Golf Tournament was played at Congressional Country club, with prizes ranging from $465,000 for first place to $5000. Par for the course is 70. The tournament consists of four rounds played on different days. Suppose the scores for each round of the 32 players who placed in the money (more than $17,000) were given on a web site. The scores for the first round were as follows: 71 66 68 72 74 73 71 71 74 73 73 71 75 71 72 71 78 75 71 71 74 75 66 75 75 76 71 72 72 73 71 67
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).
