In a random sample of 519 judges, it was found that 285 were introverts.
(a) Let p represent the proportion of all judges who are introverts. Find a point estimate for p.
(b) Find a 99% confidence interval for p. Give a brief interpretation of the meaning of the confidence interval you have found.
(c) Do you think the conditions np > 5 and nq > 5 are satisfied in this problem? Explain why this would be an important consideration.
