Chapter 9, Problem 123E(choose chapter or problem)
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):
The median titanium content should be .
(a) Use the sign test with \(\alpha=0.05\) to investigate this hypothesis. Find the P-value for this test.
(b) Use the normal approximation for the sign test to test \(H_0\ :\tilde{\ \mu}=8.5\) versus \(H_0\ :\ \tilde{\mu}\ne 8.5\) with \(\alpha=0.05\). What is the P-value for this test?
