Appraise the following regression equation based on (1)the Y-intercept and regression coefficients, (2)t-statistic and standard error, 3) sample size, 4)R-squared and Significance F, 5) model-fit from a statistical perspective. ( a 20 marks question)

=12 - 2.5 X₁+ 0.4 X₁+ 81 X₁ R-squared = 0.35(Significance F = .037)

(5.0)(0.016)(100)n = 25

t = -0.52.50.8
