A) construct an 80%, 90%, 95%, 98%, 99% confidence interval toestimate the proportion of countries in the world with an averageincome greater than the global average. Calculate theMargin of Error for each confidenceinterval.

B) As the confidence level increases, what happens to the widthof the interval? (Note: the width of the interval is the differencebetween the upper and lower limits.)

C) As the confidence level increases, what happens to the marginof error?
