1. Using the following table of relation between X & Y (Y is the independent Variable):

xi -2 2 4 5 4 6 7 8 11

yi -4 1 3 1 3 8 10 20 30

a. Find the estimated regression equation. Show ALL your calculations and the appropriate formula. WRITE Formula in all the questions below and substitute for the numbers, demonstrate your work.

b. Calculate R2. Comment on the Goodness of the Fit. Is it a good fit? Why?

c. Test the hypothesis regarding the significance of the slope β1. (Use α = 0.05) Show ALL the calculations necessary to get your answer. Hint: You need to calculate t by using all the formulas needed for it using t in the Formula Sheet.

d. Calculate the values of F, using formula for F statistics. e. Draw the scatter diagram and also your estimated regression line in a diagram.
