Question
For numbers 20-22, refer to the given problem below. Suppose a study found that 68% of the population owns a home. In a random sample of 150 households, 92 own a home. Use a = 0.01 to determine that there is a decrease in the proportion of population that owns a home. 20. Find the z-score. A. -1.75 B. -0.08 C. 0.08 D. 1.75 21. Which value is closest to the p-value? A. 0.02 B. 0.04 C. 0.06 D. 0.08 22. What is the correct decision? A. It cannot be concluded. B. Reject the null hypothesis. C. Fail to reject the null hypothesis. D. Accept both Null and Alternative Hypothesis For numbers 23-25, 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%? 23. Choose the correct hypotheses. A. Ho: p = 0.27; Ha: p > 0.27 C. Ho: p = 0.27; Ha: p # 0.27 24. What is the value of z? B. Ho: p = 0.27; Ha: p < 0.27 D. Ho: p > 0.27; Ha: p = 0.27 A. -2.59 B. -0.005 D. 2.59 C. 0.005
