In a sample of 183 male job-holders, 55% said that they are satisfied with their jobs. In another sample of 171 female job-holders, 65% said that they are satisfied with their jobs. The null hypothesis is that the proportions of all female and all male job-holders who are satisfied with their jobs are equal. The alternative hypothesis is that the proportion of all female job-holders who are satisfied with their jobs is greater than the proportion of all male job-holders who are satisfied with their jobs. The significance level is 2%. What is the approximate p-value for this test? e. 0.9732 b. 0.9975 d. 1.0000 a. 0.9139 c. 0.9724
