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:

$$\begin{array}{lll} \mbox{Pop. 1}: & n_1 = 84, & \hat{p}_1 = 0.728 \\ \mbox{Pop. 2}: & n_2 = 92, & \hat{p}_2 = 0.668 \\ \end{array}$$

Suppose that the data yields (-0.0982, 0.2182) for a confidence interval for the difference $p_1 - p_2$ of the population proportions. What is the confidence level? (Give your answer in terms of percentages.)

Confidence Level =
