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 62 professional actors, it was found that 36 were extroverts.

(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 confidence interval you have found.

A We are 95% confident that the true proportion of actors who are extroverts falls outside this interval.

B We are 5% confident that the true proportion of actors who are extroverts falls above this interval.

C We are 95% confident that the true proportion of actors who are extroverts falls within this interval.

D We are 5% confident that the true proportion of actors who are extroverts falls within 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.

A No, the conditions are not satisfied. This is important because it allows us to say that p is approximately binomial.

B No, the conditions are not satisfied. This is important because it allows us to say that p is approximately normal.

C Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately normal.

D Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately binomial.
