5. Suppose that you want to decide which of two equally-priced brands of light bulbs lasts longer. You choose a random sample of 100 bulbs of each brand and find that brand Δ has a sample mean 150 hours and a sample standard deviation of 70 hours, and that brand B has sample mean of 1170 hours and sample standard deviation of 80 hours. What decision should you make at 2% significance level?
