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:
Rain Fall, x 13.1 11.4 16.0 15.1 21.4 12.9 9.6 18.2 18.6
Yield, y 48.5 44.2 56.8 80.4 47.2 29.9 74.0 74.0 76.8
The equation of the line of least squares is given as y = -9.12 +4.38x. What would be the expected number of
inches of rain if the yield is 63 bushels of wheat per acre? Round answer to the nearest tenth
