1. 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 200 students and finds that 118 of them are receiving financial aid. By hand, and using formulas for the “Margin of Error” (i.e. not calculator confidence interval), find a 98% confidence interval to estimate the true proportion of students on financial aid. (Use 3 decimal places for proportions.) 2....

The Dean of Students at a large university wanted to estimate the proportion of students who are willing to report cheating by fellow students. So, her staff surveyed 172 students currently enrolled in the introduction to biology class. The students were asked, “Imagine that you witness two students cheating on a quiz. Would you tell the professor?” 19 of the surveyed students responded “yes.” Using these data, calculate a 95% confidence interval for the proportion of all students at the...
