According to a recent National Association of Colleges and Employers (NACE) report, 44 % of college student who had unpaid internships received full-time job offers post-graduation compared to 72 % of college student who had paid internships. A recent survey of 60 college unpaid interns at a local university found that 30 received full-time job offers post-graduation. 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 unpaid interns that received full-time job offers post-graduation is different from 0.44. b. Assume that the study found that 35 if the 60 college unpaid interns had received full-time job offers post-graduation and repeat (a). Are the conclusions the same?

28. (a) Under what conditions do we say that two random variables X and Y are
independent?
(b) Demonstrate that if X and Y are independent, then it follows that E(XY) =
E(X)E(Y);
(e) Show by a counter example that the converse of (ii) is not necessarily true.
