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

    Byx = nXY – XY / nX2 - (X) 2

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

    Byx = 0.07
    ayx = y - Byx X

    = ((Y/n) – ((0.07) (X/n))

    =(320/4) – (0.07)(1200/4)

    = 59

    y = 59 + 0.07 X is required regression equation.

    another solution
    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
    = 1200 = 320 =103000 = 460000
    Byx = nXY XY / nX2 - (X) 2
    Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2
    Byx = 0.07
    ayx = y - Byx X
    = ((Y/n) ((0.07) (X/n))
    =(320/4) (0.07)(1200/4)
    = 59
    y = 59 + 0.07 X is required regression equation.
