the standard deviation of breaking strength is 1.8 psl. A random sample of nine specimen sis tested, and the average breaking strength is found to be 100.6 psi (a) Calculate the P-value round your answer to 3 significant digits. d -0.05, should the fiber be judged acceptable? (b) What is the probability of not rejecting the null hypothesis at a 0.05 if the fiber has a true mean breaking strength of 102 psi? Round your answer to 3 significant digits.
