Extracted text: Suppose that the lifetimes of light bulbs are approximately normally distributed, with a mean of 56 hours and a standard deviation of 3.3 hours. With this information, answer the following questions. (a) What proportion of light bulbs will last between 59 and 61 hours? (b) What is the probability that a randomly selected light bulb lasts less than 45 hours? (a) The proportion of light bulbs that lasts between 59 and 61 hours is (Round to four decimal places as needed.) (b) The probability that a randomly selected light bulbs lasts less than 45 hours is (Round to four decimal places as needed.) Screenshot saved The screenshot was added to your OneDrive.
