Question
A poll found that 80% of American adults believed that there was a conspiracy in the death of President
Kennedy. A later poll asked 1097 American adults if they believe there was a conspiracy in the
assassination, and found that 834 believe there was a conspiracy. Do the data show that the proportion of
Americans who believe in this conspiracy has decreased? Test at the 1% level.
State the hypotheses.
Họ: P ?v
H,: P ?v
Calculate the test statistic. Round to four decimal places.
p =
Calculate the standardized test statistic. Round to three decimal places.
Z =
Find the p-value. Round to four decimal places.
p-value =
State your decision.
O Since the p-value is greater than .01, fail to reject Ho.
O Since the p-value is less than .01, fail to reject Ho.
O Since the p-value is less than .01, reject Họ-
O Since the p-value is greater than .01, reject Ho.
Interpret the results.
O At the 1% level of significance, there is not enough evidence to show that the proportion of American
adults who believe that there is a conspiracy in the death of President Kennedy-is more than 80%, the
value from the earlier poll.
O At the 1% level of significance, there is not enough evidence to show that the proportion of American
adults who believe that there is a conspiracy in the death of President Kennedy is less than 80%, the
value from the earlier poll.
O At the 1% level of significance, there is not enough evidence to show that the proportion of American
adults who believe that there is a conspiracy in the death of President Kennedy is not equal to 80%,
the value from the earlier poll.
O At the 1% level of significance, there is enough evidence to show that the proportion of American
adults who believe that there is a conspiracy in the death of President Kennedy is more than 80%, the
value from the earlier poll.
O At the 1% level of significance, there is enough evidence to show that the proportion of American
adults who believe that there is a conspiracy in the death of President Kennedy is less than 80%, the
value from the earlier poll.
O At the 1% level of significance, there is enough evidence to show that the proportion of American
