20 points possible 8720 answered Question 14 A poll found that 84% of American adults believed that there was a conspiracy in the death of President Kennedy. A later poll asked 1060 American adults if they believe there was a conspiracy in the assassination, and found that 869 believe there was a conspiracy. Do the data show that the proportion of Americans who believe in this conspiracy has decreased? Test at the 10% level. State the hypotheses. Ho: P ? Ha: P ? Calculate the sample proportion. Round to four decinal places. p= Calculate the test statistic. Round to three decimal places. Z = Find the p-value. Round to four decimal places. p-value= State your decision. Since the p-value is greater than .10, fail to reject Ho. Since the p-value is less than .10, fail to reject Ho Since the p-value is greater than .10, reject Ho Since the p-value is less than .10, reject Ho
