Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The critical value for the 90% confidence interval is .
