, 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:

98% confidence level

, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 98% confidence interval on the population proportion of people who like the new flavor is (0.8237, 0.8763).
