You are asked to develop a new drug that enhances memory in patients afflicted with Alzheimer's disease. In general, placebos given to such patients tend to produce a mean memory score of f = 4.6. You hypothesize that this drug produces better memory scores and carry out the experiment on a random sample of Alzheimer's patients. Test with a =0.01.
