You've been hired as a rookey process engineer in a beer manufacturing company, and your first project is to evaluate the installation of a new pump to transfer ammonia. The ammonia is used as a heat transfer fluid to control the beer fermenters temperature. It is required that the flow rate of liquid ammonia be more than 20 L/min. Data were collected in eight runs and the measured ammonia flow rates (in L/min) were tabulated below. 28.8 16.3 25.4 18.5 26.1 8.7 13.2 27.3 Hi Using the provided liquid ammonia flow rate data, your boss asks you to perform the following analyses: a. A 95% lower confidence bound. Explain why your boss is interested in this kind of bound, and not an upper bound. b. State appropriate null and alternative hypotheses. [Appropriateness is an important issue, as a hint: remember that the best possible outcome of an hypothesis test is to reject the null hypothesis. Statistically, to reject He is a robust conclusion Read the textbook.]: Ho: C. Sketch in a figure the critical region with the correct numerical values. d. Calculate the appropriate Test Statistic. e. Based on c and d above, do you reject or fail to reject the null hypothesis stated in b above? f. Estimate the p-value. ģ. Based on the p-value, do you reject or fail to reject the null hypothesis stated in b above? h. Using all results from a-g above, recommend your boss whether to put in service or not the new pump. Present your results in an adequate format, for the way you show your work will strongly determine the level of your boss' sympathy and tenure in your process engineer position.
