The percentage of female CEOs in 2013 in Fortune 500 companies was 4%, according to Time Magazine (March 18, 2013). Suppose a student did a survey of 250 randomly selected large companies (not Fortune 500 companies), and 15 of them had women CEOs. In Exercise 8.30 you carried out the first two steps to test the hypothesis that the population proportion is not 0.04. Now carry out the last two steps, using the computer output provided and a significance level of 0.05.
