Consider the data, set in the above table to estimate the regression model

Y_i = β₀ + β_lX_1i + β₂X_2i + β₃X_3i + β₄X_4i + ε_i

a. Compute b₀, b₁, b₂, b₃ and b₄.

b. Compute the predicted values for Y_i{Y_t).

c. Compute Se(b₀), Se(b₁), Se(b₂), Se(b₃) and Se(b₄).

d. Plot the residuals (e_i) against X_1i and then against Y_i

e. Test the hypothesis H₀: β₁ = 0 against H₁: β₁ ≠ 0 at 5% significance level.

f. Test the hypothesis H₀: β₄ = 1 against H1: β₄ ≠ 1 at 1% significance.

g. Compute the coefficient of determination R² and Adjusted - R²

h. Test the hypothesis that H₀: β₁ = β₂ = β₃ = β₄ = 0 against the H₁: H₀ is not true at 1% significance level.

i. Test the hypothesis that H₀: β₁ = β₂ = β₃ = 0 against the H₁: H₀ is not true at 5% significance level.

j. Test the hypothesis that H₀: β₁ = β₂ = 0 against the H₁: H₀ is not true at 1% significance level.
