To Find: The matrix that has the sum of the columns relevant and sum of the rows as relevant.

Answer to Problem 39HP
The matrix is
Explanation of Solution
Consider the matrix for the batting average for the single player represented in column and the row represents the different season.
The sum of each of the column is relevant as it is used to determine the average of all the three seasons.
The sum of the three rows is irrelevant as it has the information for multiple people.
