Question
I do not understand this problem I really need help
Transcribed Image Text: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 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?
Ô
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
H: HYPOTHESES
Fill in the correct null and alternative hypotheses:
Ho: P
HA: P
A: ASSUMPTIONS
Since qualitative
check?
Check all that apply.
