Assume a recent poll asked 1080 American adults if they believe there was a conspiracy in the assassination and it found that 821 believe there was a conspiracy. Does the data show that the proportion of Americans who believe in this conspiracy is now lower? Test at the 5% level. P: PARAMETER What is the correct parameter symbol for this problem? What is the wording of the parameter in the context of this problem? The percentage of all American adults that believe there was a conspiracy in the assassination of President Kennedy
