In 2001, the polls found that 81% of American adults believed that there was a conspiracy in the death of President Kennedy. Assume a recent poll asked 1780 American adults if they believe there was a conspiracy in the assassination and it found that 1484 believe there was a conspiracy.  Calculate a 97% confidence interval for the percentage of all Americans who believe in this conspiracy.
