7. Let p1 and p2 be the respective proportions of employees of "not-for-profit" companies and "for- profit" companies who would report a high level of job satisfaction. A researcher suspects that p1 is larger than p2, and runs a hypothesis test on a random sample of n1 = 100 and n2 = 200 employees at not-for-profit and for-profit companies respectively. If x1 = 55 of the employees in the first group and x2 = 86 of the employees in the second group express a high level of job satisfaction, what conclusion should the researcher reach? (To receive full mastery credit for this question, be sure to note the null and alternative hypotheses of the test, and clearly state the calculations that lead to the conclusion of the test.)
