Español A certain manufacturer makes 400W light bulbs. Assume that these light bulbs have lifetimes that are normally distribute with a mean lifetime of 435 hours and a standard deviation of 60 hours. Use this table or the ALEKS calculator to find the percentage of light bulbs with lifetimes longer than 501 hours. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
