A large manufacturing plant uses lightbulbs with lifetimes that are normally distributed with a mean of 1200 hours and a standard deviation of 60 hours. To minimize the number of bulbs that burn out during operating hours, all bulbs are replaced at once. How often should the bulbs be replaced so that no more than 1% burn out between replacement periods? (Round your answer to one decimal place.)
