a. Construct a 95% confidence interval estimate of the
percentage of all adults who have that belief, and then write a
statement interpreting the confidence interval.

76.1% - 82%

b. Assume that you must conduct a new poll to determine
the percentage of adults who believe that it is morally wrong to
not report all income on tax returns. How many randomly selected
adults must you survey if you want 99% confidence that the margin
of error is two percentage points?

?

c. Use the point estimate percentage from a.

?
