Life of Smoke Detectors The average lifetime of smoke detectors that a company manufactures is years, or months, and the standard deviation is months. Find the probability that a random sample of smoke detectors will have a mean lifetime between and months. Assume that the sample is taken from a large population and the correction factor can be ignored. Round the final answer to at least four decimal places and intermediate -value calculations to two decimal places.
