The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught. Step 2 of 2: Suppose a sample of 531 suspected criminals is drawn. Of these people, 201 were captured. Using the data, construct the 95% confidence interval for the population proportion of people who were caught after being on the 10 Most Wanted list.
