Suppose the U.S. president...

Suppose the U.S. president wants an estimate of the proportion of the population who

support his current policy toward revisions in the health care system. The president wants

The president’s political advisors estimated the proportion supporting the current

policy to be .60.

a. How large of a sample is required?

b. How large of a sample would be necessary if no estimate were available for the proportion

supporting current policy?
