State University uses thousands of fluorescent light bulbs each year. The brand of bulb it currently uses has a mean life of 1000 hours. A competitor claims that its bulbs, which cost the same as the brand the university currently uses, have a mean life of more than 1000 hours. The university has decided to purchase the new brand if, when tested, the evidence supports the manufacturers's claim at the 0.05 significance level. Suppose 64 bulbs were tested will the following results ī = 1027.5 hours, s = 80 hours. d. Find the rejection region for the test using a = 0.05. e. Find the p-value for the test. f. Make the appropriate conclusion using the rejection region. g. Make the appropriate conclusion using the p-value.
