| 2 | 11 | 15 | ||
| 3 | 15 | 12 | ||
| 4 | 11 | 12 | ||
| 5 | 9 | 13 | ||
| 6 | 14 | 6 | ||
| 7 | 10 | 11 |
a. Compute the difference value for each element (difference between element of population 1 and population 2 and enter negative values as negative numbers, if any). If your answer is zero, enter "0".
| Element | Difference Value |
|---|---|
| 1 | |
| 2 | |
| 3 | |
| 4 | |
| 5 | |
| 6 | |
| 7 |
