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 are actually caught. Suppose a sample of 334 suspected criminals is drawn period of these people 86 were captured. Using the data construct the 90% confidence interval for the population proportion of people who are captured after appearing on the 10 most wanted list round your answers to 3 decimal places. Lower endpoint = Upper endpoint =
