g. Use a t-test to test for significance of the intercept and slope coefficients at =0.05. Give the P-values of each and comment on your results.

h. Construct the ANOVA table and test for significance of regression using the P-value. Comment on your results and their relationship to your results in part (g).

i. Construct 95% CIs on the intercept and slope. Comment on the relationship of these CIs and your findings in parts (g) and (h).
