Two random samples are taken, with each group asked if they support a particular candidate. A summary of the sample sizes and proportions of each group answering yes'' are given below:
Pop. 1:n1=82, p^=0.809
Pop. 2:,n2=89 p^2=0.61
Suppose that the data yields (0.0804, 0.3176) for a confidence interval for the difference p1?p2 of the population proportions. What is the confidence level? (Give your answer in terms of percentages.)
