In a random sample of69professional actors, it was found that43were extroverts.

(a)Letprepresent the proportion of all actors who are extroverts.Find a point estimate forp. (Round your answer to four decimal places.)

(b)Find a 95% confidence interval forp. (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.

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.

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 within this interval.

(c)Do you think the conditionsnp>5 andnq>5 are satisfied in this problem? Explain why this would be an important consideration.
