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.”

  1. Using these data, calculate a 95% confidence interval for the proportion of all students at the university that would report cheating.
  2. Interpret the confidence interval in a sentence.
  3. Is it actually appropriate to use these data to estimate the proportion of all students at the university that would report cheating? Why or why not? (Hint: sampling.)

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. Use a 98% confidence interval to estimate the true proportion of students on 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. If the dean wanted to estimate the proportion of all students receiving financial aid to within 3% with 99% reliability, how many students would need to be sampled?

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....

Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. A.

A dean of a business school wanted to know whether the graduates of her school used the statistic skills that they learn in university during their first year of employment after graduation. As of today there are 34,050 graduates in total from the business school. The Dean is committed to allocate more funding to the development of the school’s statistics course if at least 17% of its graduates use statistics skills during their first year of employment. She surveyed 500...
