Find The Equation Of The Regression Line.?
Find the equation of the regression line. X: 0, 2, 1, 4, 8 y: 6, 5, 4, 0, 6
Y = 1.92771x + 1.67470
_____
y = βx + α
For your numbers, I get
∑x = 56, ∑y = 118,
∑xy = 1208, ∑x2 = 578, n = 6
β = (n∑xy - ∑x∑y)/(n∑x2 - (∑x)2) = 640/332
α = (∑x2∑y - ∑x∑xy)/(n∑x2 - (∑x)2) = 556/332
