Extracted text: ACTIVITY 2 - STATISTICAL ANALYSIS I. Follow the steps in testing hypothesis to answer the problem: 1. A manufacturer of flashlight batteries claims that the average life of his product will exceed 40 hours. A company is willing to buy a very large shipment of batteries if the claim is true. A random sample of 36 batteries is tested, and it is found that the sample mean is 45 hours. If the population of batteries has a standard deviation of 5 hours, is it likely that the batteries will be bought?
