Question
A statistics student is asked to estimate Y = Bo + B1X + E. She calculates the following values:
Ex = 280,
Σ(x₁ - x)² = 350, Σy, = 600, Σ(y, − y) = 1000
Σ(x,x)(y₁ - y) = -630,
n = 20
Which of the following is the sample regression equation?
OY--55.2-1.8X + e
OY 55.2 +1.8X + e
OY-55.2+1.8X + e
OY 55.2 1.8X + e
