Thirty observations were used to estimate y = 0 + 1 x 1 +

Question:

Thirty observations were used to estimate y = β₀ + β₁x₁ + β₂x₂ + ε. A portion of the Excel results is as follows:

Standard Coefficients t Stat p-value Error Intercept 21.97 2.98 7.37 6.31E-08 X1 30.00 2.23 13.44 1.75E-13 X2 -1.88 0.27 -6.96 1.75E-07

a. What is the point estimate for β₁? Interpret this value.

b. What is the sample regression equation?

c. If x₁ = 30 and x₂ = 20, what is y̅?
