He knows from numerous previous samples that this service fe is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four bulbs, with these results Samole SERVICE LIFE 1 495 505 500 505 2 525 515 505 515 3 475 185 465 475 If he uses upper and lower controllimits of 505 and 470 hours, on what samples of any does service life appear to be out of control?
