, 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:
Sampling error of 0.03.
This means that 
99.74% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
25% of all adults had used the Internet for such a purpose
This means that 
What is the sample size
The sample size is n. So
