Please answer these questions. The questions are based on business, statistic, and science classes. Please write at least 3-4 paragraph for each questions. Thank you
1. You need to estimate the mean number of travel days per year for pharmaceutical sales representatives. The mean of a small pilot study was 150 days, with a standard deviation of 14 days. If you must estimate the population mean within 2 days, how many sales representatives in the pharmaceutical industry should you sample? Use the 90 percent level.
2. The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart. The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?
3. From a systems viewpoint, what are some of the environmental issues involved in a decision by a company to outsource manufacturing operations to a foreign country? Provide some rationale based upon personal or professional experience.
4. Find three corporate vision statements and/or mission statements on the web. What values do they represent, either explicitly or implicitly? Would you want to work for these companies? Why or why not? Compare the company values with your own core values.
5. Some of the life forms on this planet are particularly harmful to others. Mosquitoes and fleas are two examples. They spread many types of illnesses, and provide very little benefit in return. If we could completely eradicate such dangerous pests, do you believe that we have the moral right to do so?
