**Question 24**
The two data sets are dependent. Find \( \bar{d} \) to the nearest tenth.
| X | 7 | 1 | 6 | 8 | 7 | 2 | 5 | 6 | 8 | 5 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Y | 9 | 4 | 9 | 7 | 8 | 7 | 6 | 9 | 3 | 7 |
\( \bar{d} \) options:
- \(-2.0\)
- \(-1.2\)
- \(+2.0\)
- \(+2.6\)
---
To calculate \( \bar{d} \), find the difference between each pair of values \((X_i - Y_i)\), sum them up, and divide by the number of pairs to find the average of differences.
The correct answer should be selected from the options provided.
