In an area of the Great Plains, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). Find the equation of the regression line for the given data.

According to me these are the values missing in the question. Here you go with the values

Rain fall, x 10.5 8.8 13.4 12.5 18.8 10.3 7.0 15.6 16.0

Wheat, y 50.5 46.2 58.8 59.0 82.4 49.2 31.9 76.0 78.8

1.440

Step-by-step explanation

9(7187.77)-(112.9)(532.8)/square root 9 (1521.39)-112.92 square root 9 (33,836.58)-532.8*532.8=453.6/square root 9.46 square root 2.06 =0.962

--Equation found in part a

11(7187.77)-(112.9)(532.8)/square root (1521.39-112.92*112.92 square root 11 (33,836.58532.8*532.8=189.1/square root 1.28 square root 1.82=1.440

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
