Solution:
We have to find: Sxx and Sxy for given pairs of data.
Formula:
![(u 11]** 3) – fix] = hiss](http://img.homeworklib.com/questions/05de0230-be34-11ea-b1a7-dd70f719fc53.png?x-oss-process=image/resize,w_560)
Thus we need to make following table:
| x | y | x2 | xy |
|---|---|---|---|
| 3 | 6 | 9 | 18 |
| 6 | 7 | 36 | 42 |
| 2 | 5 | 4 | 10 |
| 1 | 3 | 1 | 3 |
| 3 | 7 | 9 | 21 |
| 4 | 7 | 16 | 28 |
 |
