Estimate the total number as well as bound on the error of estimation for proportion.
A company auditor was attentive 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.
Evaluation the total number of vouchers that were filed incorrectly, and place a bound on the error of estimation. (HINT - If p is the proportion of incorrect vouchers, then Np is the total number of incorrect vouchers among N). Do you think that it is larger than 70? Describe.
