Question: A job training program trained thousands of participants. After the training was completed, a random sample of 64 of these participants showed that only 8 had retained jobs in which they were placed for more than 3 months. If we wished to estimate the percentage of trainees retaining jobs for more than 3 months (assuming that the 64 comprised a random sample of all trainees) with 95% confidence, what would that estimate be and what is the margin of error?
