Question:

Consider the compressive strength data in Exercise 8-37.

(a) Use the sign test to investigate the claim that the median strength is at least 2250 psi. Use 0.05.

(b) Use the normal approximation to test the same hypothesis that you formulated in part (a). What is the P-value for this test?
