(8) A melting point test of n = 10 samples of a binder used in manufacturing a rocket propellant resulted in 7 = 154.2°F. Assume that the melting point is normally distributed with o = 1.5°F. Suppose you want to test the claim that the temperature is different from 155° F. Test the hypothesis at a = 0.05 and write down the hypothesis to be tested and show all the steps and calculations. (Answer: Họ : = 155 ( = 10) H: # 155 a=0.05, 7 = 154.2,0 = 1.5, n = 10 Test statistic: 20 = 154.2-155 -1.69 1.5/10 20/2 = 20.05/2 = 1.96 Since 20 € (-70/2,2a/2) i.e. -1.69 € (-1.96, 1.96] => Accept Ho, that is the temperature is not significantly different from 155° F).
