In a study of police gunfire reports during a recent year, it was found that among 540 shots fired by New York City police, 210 hit their targets; among 283 shots fired by Los Angeles police, 80 hit their targets. We want to use a 0.05 significance level to test the claim that New York police have a higher hit rate than the Los Angeles police. Let New York police be represented by p1. Determine the p-value and if this is a right-tailed, left-tailed, or two-tailed test.
