X Y XY X2
100 70 7000 10000
200 70 14000 40000
400 80 32000 160000
500 100 5000 250000
å = 1200 å = 320 å =103000 å = 460000

Byx = nåXY – åXåY / nåX2 - (åX) 2

Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2

Byx = 0.07
ayx = y - Byx X

= ((åY/n) – ((0.07) (åX/n))

=(320/4) – (0.07)(1200/4)

= 59

y = 59 + 0.07 X is required regression equation.

Question:-
Suppose that 4 randomly chosen plots were treated with various level of fertilizer in the following yield of corn:-
Fertilizer(kg/Acre) X 100 200 400 500
Production(Bushels/Acre) Y 70 70 80 100
Estimate the Linear Regression of production Y on fertilizer X.
Solution:-
X Y XY X2
100 70 7000 10000
200 70 14000 40000
400 80 32000 160000
500 100 5000 250000
å = 1200 å = 320 å =103000 å = 460000
Byx = nåXY – åXåY / nåX2 - (åX) 2
Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2
Byx = 0.07
ayx = y - Byx X
= ((åY/n) – ((0.07) (åX/n))
=(320/4) – (0.07)(1200/4)
= 59
y = 59 + 0.07 X is required regression equation.
