The following fatigue data is obtained from spectrums of 7075-T6 test at a stress amplitude of 35 ksi. Data is in 10^6 cycles: 0.32, 1.30, 0.89, 2.70, 1.60, 1.10, 0.80, 0.52, 0.95,and 1.20. A component of 7075-T6 is subjected to this stress level for an estimated 2*10^5 cycles. Estimate the probability of failure using lognormal.
