Data was collected on two variables, \(x\) and \(y\), from eight members of a population. The data is shown in the table below.
| \(x\) | \(3.8\) | \(6.3\) | \(2.5\) | \(2.4\) | \(8.9\) | \(10.7\) | \(6.7\) | \(10.3\) |
|---|---|---|---|---|---|---|---|---|
| \(x\) | \(11.8\) | \(9.7\) | \(6.1\) | \(4.1\) | \(p\) | \(23.3\) | \(13.7\) | \(24.5\) |
Find \(\bar{x}\).
[2]The regression line of \(y\) on \(x\) for this data is \(y = 0.014375 + 2.1625x\).
Find
[4]\(\bar{y}\) ;
the value of \(p\).
Hence, find Pearson's product-moment correlation coefficient, \(r\).
