You are interested in determining whether word recall is better when (1) the words are just directly memorized or (2) a story that includes all the words is made up by the subjects. In the second method, the story, from which the words could be recaptured, would be recalled. You plan to run 14 subjects in a repeated measures experiment and analyze the data with the sign test. Each subject will use both methods with equivalent sets of words. The number of words remembered in each condition will be the dependent variable;α = 0.052 tail.

a.What is the power of the experiment to detect this large* effect ofPreal = 0.80 or 0.20?

b.What is the probability of a Type II error?
