CHAPTER INVESTIGATION
Create a 10-by-10 table for each player.
Number both the columns and rows from 1 to 10. The table represents all the
possible outcomes for a player at bat. Using the percents you calculated, fill
in the cells of the table with appropriate abbreviations. For example, in 1998
Gary Sheffield hit a home run in 5% of his at bats. To create a table for
Sheffield, you would write HR in any 5 cells.
