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 67 professional actors, it was found that 42 were extroverts. l USE SALT (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.) (b) Find a 95% confidence interval for p. (Round your answers to two decimal places.) lower limit upper limit Give a brief interpretation of the meaning of the condence interval you have found. We are 95% condent that the true proportion of actors who are extroverts falls within this interval. We are 5% confident that the true proportion of actors who are extroverts falls within this interval. \" We are 5% confident that the true proportion of actors who are extroverts falls above this interval. We are 95% condent that the true proportion of actors who are extroverts falls outside this interval. (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 satised. This is important because it allows us to say that}?! is approximately binomial. No, the conditions are not satised. This is important because it allows us to say thatf) is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say thatf) is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say thatf) is approximately binomial
