Isabel Myers was a pioneer in the study of personality types. In
a random sample of 62
professional actors, it was found that 39 were extroverts.
(a) Let p represent the proportion of all actors who are
extroverts, Find the point estimate for p.
(b) Find a 95% confidence interval for the p. Give a brief
interpretation of the meaning of the
confidence interval you have found.
(c) Do you think the conditions np greater than 5 and nq greater
than 5 are satisfied in this problem? Explain why this
would be an important consideration.
