\fA light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 765 hours. A random sample of 22 light bulbs has a mean life of 740 hours. Assume the population is normally distributed and the population standard deviation is 59 hours. At a = 0.08, do you have enough evidence to reject the manufacturer's claim?
