The titanium content in an aircraft-grade alloy is an


The titanium content in an aircraft-grade alloy is an important determinant of strength. A sample of 20 test coupons reveals the following titanium content (in percent):

8.32, 8.05, 8.93, 8.65, 8.25, 8.46, 8.52, 8.35, 8.36, 8.41, 8.42,

8.30, 8.71, 8.75, 8.60, 8.83, 8.50, 8.38, 8.29, 8.46

Use the normal approximation for the sign test to test H0 width== 8.5 versus H1: width=? 8.5, with a = 0.05. What is the P-value for this test?
