Use the figure to the right, which shows the percentages of adults from severa power plants in their country. The survey included random samples of 1034 adults from Country A, 1053 adults from Country B, 1118 adults from Country C, and 1030 adults from Country D. At a = 0.05, can you reject the claim that the proportion of adults in Country A who favor building new nuclear power plants in their country is the same as the proportion of adults from Country B who favor building new nuclear power plants in their country? ASsume the random samples are independent. 80- 60- 40- 20- 0- | Country A 48% Country B 52% O Country C 43% O Country D 36% dentify the claim and state Ho and Ha the proportion of adults from Country B The claim is "the proportion of adults in Country A who favor building new nuclear power plants in their country is who favor building new nuclear power plants in their country."

Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples of 1034 adults from Country A, 1053 adults from Country B, 1118 adults from Country C, and 1030 adults from Country D. At a = 0.05, can you reject the claim that the proportion of adults in Country A who favor building new nuclear power plants in their country is the same as the proportion of adults from Country B who favor building new nuclear power plants in their country? Assume the random samples are independent. 100- 80- 60- 40- 20- 0- | Country A 48% Country B 52% O Country C 43% O Country D 36% Identify the claim and state Ho and Ha V the proportion of adults from Country B The claim is "the proportion of adults in Country A who favor building new nuclear power plants in their country is who favor building new nuclear power plants in their country." Let p, represent the population proportion for Country A and p2 represent the population proportion for Country B. State Ho and Ha- Choose the correct answer below. OC. Ho: P1 SP2 Ha: P1 > P2 O B. Ho: P1 <P2 O A. Ho: P1 = P2 Ha: P1 P2 Ha: P1 2 P2 OF. Ho: P12P2 O E. Ho: P1 # P2 Ha: P1 = P2 O D. Ho: P1> P2 Ha: P1 <P2 Ha: P1 SP2 Find the standardized test statistic. z= (Round to two decimal places as needed.) Use technology to calculate the P-value. P-value = (Round to three decimal places as needed.) e 3D Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O Reject Ho because the P-value is less than the significance level a. Fail to reject Ho because the P-value is less than the significance level a. O Fail to reject H, because the P-value is greater than the significance level a. O Reject Ho because the P-value is greater than the significance level a. Can you reject the original claim? Choose the correct answer below. O A. Yes, at the 5% significance level, there is sufficient evidence to reject the claim. O B. Yes, at the 5% significance level, there is insufficient evidence to reject the claim. O C. No, at the 5% significance level, there is sufficient evidence to reject the claim. O D. No, at the 5% significance level, there is insufficient evidence to reject the claim.
