/202 /202 For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. 10/201 19/20 In a random sample of 63 professional actors, it was found that 44 were extroverts. 16/20 (a) Let p represent the proportion of all actors who are extroverts. Find a point estimate for p. (Round your answer to four decimal places.) /16/20 3/19/20 (b) Find a 95% confidence interval for p. (Round your answers to two decimal places.) 4/19/20 lower limit 3/16/20 upper limit Give a brief interpretation of the meaning of the confidence interval you have found. O We are 5% confident that the true proportion of actors who are extroverts falls above this interval. We are 95% confident that the true proportion of actors who are extroverts falls outside this interval. We are 5% confident that the true proportion of actors who are extroverts falls within this interval. O We are 95% confident that the true proportion of actors who are extroverts falls within this interval. (c) Do you think the conditions n.p > 5 and n.q > 5 are satisfied in this problem? Explain why this would be an important consideration. Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately normal. O No, the conditions are not satisfied. This is important because it allows us to say that p is approximately binomial. O Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately binomial. O No, the conditions are not satisfied. This is important because it allows us to say that p is approximately normal.
