Refer to the Psychological Science (Aug. 2011) study of fingerprint identification, Exercise 4.74 (p. 212). Recall that the study found that when presented with prints from the same individual, a novice will correctly identify the match only 75% of the time. Now consider a sample of 120 different pairs of fingerprints where each pair is a match.
a. Estimate the probability that a novice will correctly identify the match in more than half of all pairs of fingerprints.
b. Estimate the probability that a novice will correctly identify the match in fewer than 100 pairs of fingerprints?
