Question

Refer to the Psychological Science (Aug. 2011) study of fingerprint identification. Recall that when presented with prints from the same individual, a fingerprint expert will correctly identify the match 92% of the time. Consider a forensic data base of 1,000 different pairs of fingerprints, where each pair is a match. What is the probability that an expert will correctly identify fewer than 900 of the fingerprint matches?

Given:

p=Probability of success=92%=0.92n=Sample size=1000x=Number of successes=900\begin{align*} p&=\text{Probability of success}=92\%=0.92 \\ n&=\text{Sample size}=1000 \\ x&=\text{Number of successes}=900 \end{align*}

The sampling distribution of the sample proportion p^\hat{p} has mean pp and standard deviation p(1p)n\sqrt{\frac{p(1-p)}{n}}.
