The lifespan of xenon metal halide arc-discharge bulbs for aircraft landing lights is normally distributed with a mean of 2,600 hours and a standard deviation of 550 hours.
Required:
a. If a new ballast system shows a mean life of 3,143 hours in a test on a sample of 12 prototype new bulbs, would you conclude that the new lamp’s mean life exceeds the current mean life at α = 0.05?
b. What is the p-value?
