Question 1

One ESP test asks the subject to view the backs of cards and identify whether a circle,

square, star, or cross is on the front of each card. If p is the proportion of correct

answers, this may be viewed as a hypothesis test with He: p=0.25 and H:p>0.25.

The subject is recognized to have ESP when the null hypothesis is rejected. What

would a Type II error result in?

(A) Correctly recognizing someone has ESP

(B) Mistakenly thinking someone has ESP

(C) Not recognizing that someone really has ESP

(D) Correctly realizing that someone doesn't have ESP

(E) Failing to understand the nature of ESP
