Find a point estimate for p. [Round your answer to four decimal places.) E (b) Find a 95% condence interval for p. [Round your answers to two decimal places.) lower limit upper limit lGive a brief interpretation of the meaning of the condence interval you have found. C We are 5% condent that the true proportion of actors who are extroverts falls above this interval. D We are 95% condent that the true proportion of actors who are extroverts falls outside this interval. 0 We are 95% condent that the true proportion of actors who are extroverts falls within this interval.

Explain why this would be an important consideration. 0 Yes, the conditions are satised. This is important because it allows us to say that g) is approximately nonnal. D Yes, the conditions are satised. This is important because it allows us to say that is approximately binomial. O No, the conditions are not satised. This is important because it allows us to say that :3 is approximately binomial. O No, the conditions are not satised. This is important because it allows us to say that :3 is approximately normal
