  2. Calculate the coefficient of determination.
  3. What percentage of the variability of Rating can be explained by its linear relationship with Price? What is the sample correlation coefficient?
  4. What is the estimated regression equation?
  5. 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.
