figure to the nght, hich shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples of 1125 adults from Country A, 1003 adults from Country B, 1019 adults from Country C, and 1070 adults from Country D. At a=0.06, can you reject the claim that the proportion of adults in Country C who favor building new nuclear power plants in their country is greater than the proportion of adults from Country D who favor building new nuclear 80- power plants in their country? Assume the random samples are independent. 100- 60- 40- 20 I Country A 51% ICountry B 48% O Country C 46% O Country D 36% Use technology to calculate the P-value. P-value = (Round to four decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O Reject Ho because the P-value is greater than the significance level a. O Fail to reject H, because the P-value is less than the significance level a. O Reject Ho because the P-value is less than the significance level a. O Fail to reject Ho because the P-value is greater than the significance level a. Can you support the original claim? Choose the correct answer below.

Question
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 1125 adults from Country A, 1003 adults from Country B, 1019 adults from Country C, and 1070 adults from Country D. At a =0.06, can you reject the claim that the proportion of adults in Country C who favor building new nuclear power plants in their country is greater than the proportion of adults from Country D who favor building new nuclear 80- 100- power plants in their country? Assume the random samples are independent. 60- 40- 20- 0- I Country A 51% I Country B 48 % O Country C 46% O Country D 36% Use technology to calculate the P-value. P-value = (Round to four decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O Reject Ho because the P-value is greater than the significance level a. O Fail to reject Ho because the P-value is less than the significance level a. O 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. Can you support the original claim? Choose the correct answer below. O A. No, at the 6% significance level, there is sufficient evidence to reject the claim. O B. Yes, at the 6% significance level, there is insufficient evidence to reject the claim. O C. Yes, at the 6% significance level, there is sufficient evidence to support the claim. O D. No, at the 6% significance level, there is insufficient evidence to support the claim. O Time Remaining: 01:52
