(The margin of error of 95% confidence I found was + or - 2%)
a.) If we only require to be 90% confident, will the margin or error be larger or smaller? explain.
b.) Find out that margin of error. (90% confident margin of error)
c.) In general, if all other features of the situation remain the same, would smaller samples produce smaller or larger margins of error?
