An electric firm manufactures light bulbs that have a lifetime measured in days that is approximately normally distributed with unknown mean μ and standard deviation of 16 days. A quality engineer takes a random sample of size n = 16, so that, after setting the probability of committing a Type I error at the level α = 0.05, he can test the null hypothesis Hoμ = 100, against the alternative hypothesis that Ha : μ > 100. == What is the power of the hypothesis test if the true population mean were μ = 108 ?
