You are considering testing a new drug that is supposed

to facilitate learning in mentally retarded children. Because there is relatively little known about the drug, you plan to use a no directional alternative hypothesis. Your resources are limited, so you can test only 15 subjects. The subjects will be run in a repeated measures design and the data analyzed with the sign test using??=0.052 tail. If the drug has a medium effect on learning such thatPreal = 0.70, what is the probability you will detect it when doing your experiment? What is the probability of a Type II error?
