Step-by-step explanation:
Information given:
represent the sample size
represent the estimated proportion
The confidence interval would be given by this formula
For the 98% confidence interval the value of 
and 
, with that value we can find the quantile required for the interval in the normal standard distribution.
And replacing into the confidence interval formula we got:
And the confidence interval would be:
