Answer to Problem 25E
We should not take retest.
Explanation of Solution
It is given that people who claim to “have ESP” participate in a screening test in which they have to guess which of several images someone is thinking of. We took the test. We scored two standard deviations above the

Answer to Problem 25E
The friend should retake the test.
Explanation of Solution
It is given that people who claim to “have ESP” participate in a screening test in which they have to guess which of several images someone is thinking of. We took the test. We scored two standard deviations above the mean and friend scored one standard deviation below the mean. So, the researcher offer everyone the opportunity to take the retest. Thus, the friend should probably retake the test, as his score is better than only about
