A company produces light bulbs with a mean lifetime of 800 hours and a standard deviation of 100 hours. What is the probability that a randomly selected bulb will have a lifetime of at least 1000 hours? If a sample of 36 bulbs is selected, what is the probability that the mean lifetime of the sample will be less than 780 hours?
