Question: Exercise 11-11 presented data on y = chloride concentration in surface streams and x = roadway area. (a) Test the hypothesis H0: B1 = 0

Exercise 11-11 presented data on y = chloride concentration in surface streams and x = roadway area.
(a) Test the hypothesis H0: B1 = 0 versus H1: B1 = 0 using the analysis of variance procedure with a = 0.01.
(b) Find the P-value for the test in part (a).
(c) Estimate the standard errors of and
(d) Test H0: B0 = 0 versus H1: B0 = 0 using a = 0.01. What conclusions can you draw? Does it seem that the model might be a better fit to the data if the intercept were removed?
