Find the sample size in order to obtain p estimate

A company auditor was interested in estimating the total number of travel vouchers that were incorrectly filed. In a SRS of size n =50 oft of the group of N = 250, were filed incorrectly.

How large sample should be selected in order to obtain p estimate with a bound of 0.08 on the error of estimation.

(a) Use the data already collected to determine the bound for the further study.

(b) Do not use the information provided above.
