Consider a simple linear regression model, Y₁ = ß₁ + ß₁X; + &; for i = 1,2,...,n with the usual random error term (₁) assumptions. Suppose that hypotheses Ho: P₁ = 0 against H₁:₁ <0 were tested and Ho: B₁ = 0 was rejected. Assume ₁ e₁² = 0. i) Briefly explain what the conclusion of the test means for the values of Y given the values of X. ii) Draw an example of a scatter plot with the fitted regression line for the problem mentioned above. iii) Calculate and interpret the correlation coefficient for the problem at hand.
