Question
A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 769 hours. A random sample of 29 light bulbs has a mean life of 756 hours. Assume the population is normally distributed and the population standard deviation is 64 hours. At a = 0.02, do you have enough evidence to reject the manufacturer's claim? Complete parts (a) through (e). (a) Identify the null hypothesis and alternative hypothesis. OA. Ho: <756 (claim) Hgi με 756 OD.
