We are studying two potential gold orebodies which are located side-by-side in the same regional-scale igneous complex. We have the results from 20 assays for the first ore-body and 10 assays for the second orebody. The assays for the first orebody showed a sample standard deviation of s1 = 1 ppm, while the second showed a sample standard deviation of s2 = 1.5 ppm. a) If we assume σ1 = σ2, what is the F value that corresponds to our observed outcome? You should set up the F calculation such that a value greater than 1 is obtained. b) If we assume σ1 = σ2, what is the approximate probability we would observe a ratio of s22/s12 as large as we did? c) Could we reject the null hypothesis Ho: σ1 = σ2 in favor of the alternative hypothesis Ha: σ1 < σ2 at the 5% significance level based on the above result?

You are a plant manager at a manufacturing company. Relationship between your management team and factory workers is generally harmonious. You and the other managers have worked your way up through the company so you understand the demands of your workers' jobs, and you have done your best to create a culture of togetherness at the plant. While in the break room one afternoon, you find out that one of the line workers, Mary Chan, has started talking to other employees about unionizing the factory. She wants to start an organizing committee to discuss labor issues at the plant and figure out how the plant's workers could start or join a union. You have nothing against unions, but you don't understand why one would be necessary at your plant. You are worried that having a union would create a lot of tension in the plant and create a more adversarial environment that would ultimately result in lower productivity and profits. You feel really disappointed because everyone seemed so happy. You are thinking about inviting Mary out to lunch to dissuade her from her union effort. Should you do this? If so, what should you say to Mary?
