11. [-/5 Points] DETAILS BBUNDERSTAT12 7.3.012.MI.S. For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. In a random sample of 532 judges, it was found that 283 were introverts. USE SALT MY NOTES ASK YOUR TEACHER (a) Let p represent the proportion of all judges who are introverts. Find a point estimate for p. (Round your answer to four decimal places.) (b) Find a 99% confidence interval for p. (Round your answers to two decimal places.) lower limit upper limit Need Help? Give a brief interpretation of the meaning of the confidence interval you have found. We are 99% confident that the true proportion of judges who are introverts falls outside this interval. We are 1% confident that the true proportion of judges who are introverts falls within this interval. We are 99% confident that the true proportion of judges who are introverts falls within this interval. We are 1% confident that the true proportion of judges who are introverts falls above this interval. Submit Answer PRACTICE ANOTHER (c) Do you think the conditions np > 5 and nq > 5 are satisfied in this problem? Explain why this would be an important consideration. No, the conditions are not satisfied. This is important because it allows us to say that p is approximately binomial. Yes, the conditions are satisfied. This is important because it allows us to say that ô is approximately normal. No, the conditions are not satisfied. This is important because it allows us to say that p is approximately normal. o Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately binomial.
