35. According to a recent report, 48% of college student internships are unpaid. A recent survey of 60 college interns at a local university found that 40 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.
Let π be the population proportion. Determine the null hypothesis and the alternative hypothesis.
What is the test statistic?
What is the p-value?
What is the final conclusion?
b. Assume that the study found that 53 of the 60 college interns had unpaid internships and repeat (a). What is the test statistic?
What is the p-value?
What is the final conclusion?

government leaders attending a large national leadership conference
and that 57 were found to be extroverts. Does this indicate that
the population proportion of extroverts among college student
government leaders is different (either way) from 82%? Use
α = 0.01.
