Question
100%

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 1500 American adults if they believe there was a conspiracy in the assassination and it found that 1180 believe there was a conspiracy.  Calculate a 91% confidence interval for the percentage of all Americans who believe in this conspiracy.

A: Assumptions
• Since Select an answer information was collected from each object, what conditions do we need
to check? Check all that apply.
On 30 or normal population.
ON > 20n
Oo is unknown.
