The tables below compare the batting performances for selected years for two well-known former baseball players, Babe Ruth and Mickey Mantle.

(a) For each player, compute the batting average percent (pct.) for each year by dividing the number of hits by the number of at bats. Round to the nearest thousandth. Place the answers in the pct. column. 

(b) Going across each of the five horizontal lines (for example Ruth, 1925, vs. Mantle, 1954), compare the percents (pct.) and determine which is greater in each case. 

(c) For each player, compute the mean batting average percent for the 5 given years by dividing the total hits by the total at bats. Which is greater, Ruth’s or Mantle’s?

(d) Find the mean percent for each player by adding the five pcts. and dividing by 5. Which is greater, Ruth’s or Mantle’s?
