Question: 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 non directional alternative hypothesis. Since your resources are limited, you can test only fifteen subjects. The subjects will be run in a repeated measures design & the data will be analyzed with the sign test, using a = 0.052 real

[A] Find the probability of making a Type II error? [Please show all your work.]
[B] If the drug has a medium effect on learning such that preal - 0.70, Find the probability you will detect the effect when doing your experiment?
