A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 168 students and finds that 109 of them are receiving financial aid. Use a 95% confidence interval to estimate the true proportion of students who receive financial aid. Write the LOWER BOUND for the confidence interval. Round to the nearest thousandth.
