CH8: Please assist Dr. Valerie in calculating the power of the following anticipated experiment with n 30 from a normally-distributed population with u = 80 and o = 13. You have already calculated that standard error is OM = 2.37. If the treatment is expected to increase scores by 10 points, what is the power (in probability terms) of a two-tailed hypothesis test using a = .05? O a. 0.0119 Оb. -0.3096 Oc. -0.0119 Od. 0.9881 O e. 0.3096 е.
