One proposal that received little attention from Major League Baseball is to pay pitchers according to the following rule: each pitcher receives a base salary of $4.25 million, minus $0.25 million times his earned run average (ERA). A lower ERA is associated with better performance. If this rule were adopted, what would be the correlation between a pitchers earnings and ERA (indicate the strength and direction only theres no need to calculate the correlation)? Assume that ERA cannot exceed 17, so this rule never results in negative earnings.
