In the game of baseball, the objective of the offense is to score runs. There are several secondary ways to measure the efficiency of offenses in baseball. Batting average (BA) measures what percentage of the time batters reach base via a hit, slugging average (SLG) measures the ability of a team to hit for power, on-base percentage (OBP) measures a team’s ability to reach base via hits and walks, and OPS is on-base percentage plus slugging average. Below is the data for baseball’s national league in 2011.

he regression line relating runs scored and batting average is given by

R= ?  *BA + ?


The correlation coefficient between R and BA is  ?


Predict the number of runs scored by a team whose BA was .255. Round your answer to the closest whole number. 


Predict the number of runs scored by a team whose BA was .000. Round your answer to the closest whole number. 


Obviously the answer above makes no sense, and this is (in part) because no team in our data had a BA anywhere near .000. This is a textbook illustration of what term from the course?
