A fatigue test is performed on 85 rotating beam specimens made of 5160H steel, where the specimens are subject to a cyclic load that causes tensile and compressive stresses of equal magnitude. The number of cycles to failure for this population of specimens follows a Gaussian distribution with mean 130 cycles and standard deviation of 50 cycles. a) What is the probabilty that a specimen would fail at 95 cycles or less
