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 66 professional actors, it was found that 43 were extroverts.   (a) Let p represent the proportion of all actors who are extroverts. Find point estimates for p and q. (Round your answer to four decimal places.)   p̂= q̂=   (b) Find a 95% confidence interval for p.   Find the maximal margin of error. (Round your answer to two decimal places.)   E =    Report the bounds from the 95% confidence interval for p. (Round your answers to two decimal places.)   lower limit = upper limit =
