a.

Explanation of Solution
Given information: a table is given showing U.S High school sports participation in 2005 and 2006
Calculation:
Change in participation from year 2005 to 2006 has been calculated as follows:
Sport | 2005 | 2006 | Change in participation |
Baseball | 461 | 472 | 472 − 461 = 11 |
Basketball | 1002 | 999 | 999 − 1002 = - 3 |
Softball | 366 | 370 | 370 − 366 = 4 |
Football | 1047 | 1073 | 1073 − 1047 = - 26 |
Gymnastics | 21 | 19 | 19 − 21 = - 2 |
Hockey | 44 | 43 | 43 − 44 = - 1 |
Tennis | 318 | 327 | 327 − 318 = 9 |

Answer to Problem 35PPS
Total change in participation related to the given sports from 2005 to 2006
Explanation of Solution
Calculation:
From part a.,
Sport | 2005 | 2006 | Change in participation |
Baseball | 461 | 472 | 472 − 461 = 11 |
Basketball | 1002 | 999 | 999 − 1002 = - 3 |
Softball | 366 | 370 | 370 − 366 = 4 |
Football | 1047 | 1073 | 1073 − 1047 = - 26 |
Gymnastics | 21 | 19 | 19 − 21 = - 2 |
Hockey | 44 | 43 | 43 − 44 = - 1 |
Tennis | 318 | 327 | 327 − 318 = 9 |
So,
Total change in participation related to the given sports from 2005 to 2006
