3) A local politician, running for reelection, claims that the mean prison time for car thieves is less than the required 6 years. A sample of 80 convicted car thieves was randomly selected, and the mean length of prison time was found to be 5 years and 6 months (i.e.5.5), with a population standard deviation of 1 year and 5 3 months (ie. 1.25). At a=0.05, test the politician's claim. (use rejection region method)
