a. Use the critical value approach to perform an F test for the significance of the linear relationship between Rating and Price at the 0.05 level of sig.
b. Calculate the coefficient of determination
c. What is the estimated regression equation?
d. Use the p-value approach to perform a t test for the significance of the linear relationship between Price and Rating at the 0.05 level of significance.

Use regression analysis to examine the variation in a dependent variable.  Use 0.05 level of significance unless other stated. When doing various tests (fit, significance) report the relevant values of the parameters (test stats, R square) Make sure to write out your hypotheses and rejection rules for significance tests.  If p-values are greater than 0 report the level at which your test is significant. Conclusions are to be in terms of the problems; pretend the reader has no idea about you were...
