2-Proportion Test
In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Question

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 152 students and finds that 101 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.
