The professor teaching the Introductory Statistics class discussed in Exercise 55 wonders whether performance on homework can accurately predict midterm scores.
In Exercise 55

a) To investigate it, she fits a regression of the sum of the two midterm€™s scores on homework scores. Fit the regression model.
b) Comment on the model including a discussion of the assumptions and conditions for regression. Is the coefficient for the slope "statistically significant"?
c) Do you think she can accurately judge a student's performance without giving the midterms? Explain.
