-In an area of Russia, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre) . The data for a 9 year period is as follows:
$\begin{array}{l|ccccccccc}\text { Rain Fall, x } & 13.1 & 11.4 & 16.0 & 15.1 & 21.4 & 12.9 & 9.6 & 18.2 & 18.6 \\\hline \text { Yield, y } & 48.5 & 44.2 & 56.8 & 80.4 & 47.2 & 29.9 & 74.0 & 74.0 & 76.8\end{array}$

The equation of the line of least squares is given as $\mathrm { y } = - 9.12 + 4.38 \mathrm { x }$ . What would be the expected number of inches of rain if the yield is 60 bushels of wheat per acre?
