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 zscore that has a pvalue of
.
For this problem, we have that:

, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
