Part A: Write the equation of the regression line using the regression output. (2 points)

Part B: What do the slope and intercept parameters mean using the context of the problem? (4 points)

Part C: Compute the margin of error that Hawk should use if he wants to provide a 99% confidence interval for the slope. Assume that conditions for inference are satisfied. (4 points)
