According to a recent report, 45% of college student internships are unpaid. A recent survey of 120 college interns at a local university found that 70 had unpaid internships. a. Use the five-step p-value approach to hypothesis testing and a 0.01 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 59 of the 120 college interns had unpaid internships and repeat (a). Are the conclusions the same? a. Let z be the population proportion. Determine the null hypothesis, Ho, and the alternative hypothesis, H1. Ho: V (Type integers or decimals. Do not round.)
