According to a recentreport, 48% of college student internships are unpaid. A recent survey of 80 college interns at a local university found that 41 had unpaid internships.

a. Use thefive-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 50 of the 80 college interns had unpaid internships and repeat(a). Are the conclusions thesame?

Let be the population proportion. Determine the nullhypothesis, H0, and the alternativehypothesis, H1.

H0: ___

H1: ___
