, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
In this question:
The margin of error is of 0.0184 = 1.84%.
Ths would be (220 - 315 )* 100
