According to a recent National Association of Colleges and Employers (NACE) report, 48% of college student internships are unpaid. (Source: “Just 38 Percent of Unpaid Internships Were Subject to FLSA Guidelines,” bit.ly/Rx76M8.) A recent survey of 60 college interns at a local university found that 30 had unpaid internships.
a. Use the five-step p-value approach to hypothesis testing and a 0.05 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.48.
b. Assume that the study found that 37 of the 60 college interns had unpaid internships and repeat (a). Are the conclusions the same?
