We are estimating the spares requirement for a radar power supply. The power supply was designed with a mean (μ) life of 6500 hours. The standard deviation (σ) determined from testing is 750 hours. What is the likelihood that a power supply would fail in less than 4880 hours?© BrainMass Inc. brainmass.com September 20, 2018, 7:10 am ad1c9bdddf - https://brainmass.com/statistics/conditional-probability-distribution/calculating-probability-under-a-standard-normal-curve-582951
The solution gives detailed steps on calculating the likelihood that a power supply would fail in less than 4880 hours under a standard normal curve.
