The mean breaking strength of yarn used in manufacturing drapery material is required to be at least 100 psi. past experience has 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?
