For numbers 12-15, refer to the given problem below. Suppose that the percentage of female physicians is 27%. In a survey of physicians, 45 of 120 are women. Is there sufficient evidence at a = 0.01 to claim that the proportion of women physicians is greater than 27%? 12. Choose the correct hypotheses. A. Ho: p = 0.27; H₁: p > 0.27 B. Ho: p = 0.27; Ha: p < 0.27 C. Ho: p = 0.27; Ha: p * 0.27 D. Ho: p > 0.27; Ha: p = 0.27 13. What is the value of z? A. -2.59 B. -0.005 C. 0.005 D. 2.59 14. Which is closest to the p-value? A. 0.0005 B. 0.005 C. 0.05 D. 0.5 15. What is the correct decision and conclusion? A. Change the alternative hypothesis. B. There are no possible decision and conclusion. C. Reject the null hypothesis because there is enough evidence to support the claim that the proportion of women physicians is greater than 27%. D. Fail to reject the null hypothesis because there is not enough evidence to support the claim that the proportion of women physicians is greater than 27%.
