Question
According to a recent report,
45%
of college student internships are unpaid. A recent survey of
80
college interns at a local university found that
39
had unpaid internships.a. Use the five-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
0.45.
b. Assume that the study found that
46
of the
80
college interns had unpaid internships and repeat (a). Are the conclusions the same?Question content area bottom
