According to a recentreport, 47% of college student internships are unpaid. A recent survey of 120 college interns at a local university found that 68 had unpaid internships.

a. Use thefive-step p-value approach to hypothesis testing and a 0.10 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.47.

b. Assume that the study found that 60 of the 120 college interns had unpaid internships and repeat(a). Are the conclusions thesame?

A) Let (pi.) be the population proportion. Determine the null hypothesis, H_o , and the alternative hypothesis H₁.

H_o:(pi) = .47

H₁:(pi)-(not=).47
