The mean breaking strength of yarn used in manufacturing drapery material is required to be at least 100 psi. Past experience ha
s indicated that the standard deviation of breaking strength is 3.0 psi. A random sample of 9 specimens is tested, and the average breaking strength is found to be 100.6 psi. (a) Calculate the P-value. Round your answer to 3 decimal places. (b) If α = 0.05, should the fiber be judged acceptable?
