Each job opening on average attracted 250 resumes. You know the job market improved next year which means more people switching jobs and fewer uemployed workers. To find out which trend is stronger, you take a random sample of 20 employers and asked how many resumers they received. 212, 228, 208, 260, 280, 204, 220, 244, 196, 244 216, 256, 176, 228, 220, 240, 212, 244, 204, 224 With alpha = .05 a) State the null and alternative hypothesis. b) Does the sample provide enough evidence that the number of resumers changed.
