A synthetic fiber used in manufacturing carpet has a tensile strength that is normally distributed with a mean 75.5 psi and standard deviation 3.5 psi. Find the probability that a random sample of n = 6 fiber specimens will have a mean sample tensile strength that exceeds 75.75 psi. Express the final answer to four decimal places (e.g. 0.9876). i 0.5695
