Question 3:

From the data below;

x1 1 2 3 4 5

y1 3 7 5 11 14

a) Compute the mean square error

b) Compute the standard error of the estimate

c) Compute the estimated standard deviation of b1

d) Use the t-test to test the following hypothesis (α= .05)

Ho: β1 = 0

Ha: β1 ≠ 0

e) Use the F-test to test the hypotheses in part (d) at a 0.5 level of significance. Present in the analysis of variance format.
