Yоu hаve а sаmple оf data where each data pоint corresponds to the total number of insurance claims a customer has filed and whether the customer has experienced a policy cancellation (1 = policy canceled, 0 = policy not canceled). You ran a logistic regression analysis to predict the probability of policy cancellation based on the number of claims filed. Your regression coefficient (b1b_1) is 0.37. Which of the following is the correct interpretation of this?
Chаpter 9 cоvered sоme Mаintenаnce and Reliability Best Practices. There's a Key Benchmarks diagram оn p. 304 in that book.Below are two organizations. They are both doughnut manufacturers, and use heavy machinery to fry their goods. Organization A is a craft production unit. They estimate they spend 5 cents per dozen doughnuts on maintenance costs, but part of this is due to their highly trained workforce. The workforce undergoes one full week (40 hours) of paid training each year. This has translated into a modest injury rate; they sustain approximately 1 or 1.5 injuries per 100 full-time equivalents per year (assume a full time worker is 2,000 hours). This training has also extended to their CMMS system; 19 out of every 20 items are carefully recorded in the CMMS. (The last one is just done quietly on the run.) Due to their craft production they do suffer from somewhat high rates of muda (waste), and also need to work on the 5S, especially the sweeping. They make doughnuts 365 days a year, and they were not operational due to machine failure on approximately 22 of those days. They do a root cause failure analysis on most (approximately 4 out of 5) of their failures, and detect approximately 70% of their failures prior to actual failure. (The other 30% of the time, they just plain old melt down.) Their estimate of lambda (the failure parameter) is about 0.05, which is really quite low all things considered.Organization B is a mass production unit for the same type of doughnut. They hire fairly unskilled labor, and invest in modest training - generally about three full days, spread over the year of employment. Because they have invested in industrial-strength doughnut machines, they estimate their unscheduled downtime is about 5%, and everything gets logged in the CMMS system (well over 99%). Deming would approve of management's approach to the workers; management is forever encouraging them to help improve the system. They think they spend about 15% of their maintenance hours doing reactive work, in which they actually stop the production line to fix something. They get their doughnut inventory turned over entirely approximately 12 times per year, which is only feasible because it can be frozen. Their maintenance inventory turns over much less frequently, perhaps 2 or 2.5 times per year. Much of this workforce is either Baby Boomers (in management) or Generation Y (on the machines). They have just started to do root cause failure analysis on their most massive failures, and estimate it happens about 20% of the time.Use the Key Benchmarks to compare the two organizations. Which organization is doing better in its Maintenance and Reliability, and why do you say that?
Pаrt 3 Essаy Questiоn [40%]:Yоur essаy shоuld have an introduction with a clear and specific thesis, a body with evidence, and a conclusion that reinforces your central argument. Select the option you feel the most comfortable with and answer it to the best of your ability.Choose ONE (1) of the following options: Compare and contrast two of the largest union-organizing institutions in the United States during the Progressive Era: the AFL and the IWW. What were the AFL and the IWW; what did they stand for, what were their aims, and how did they both seek to achieve their goals? To which group of workers did each group appeal? Why would many corporations of the time have seen the IWW as a particularly threatening and subversive group?What Horror Trope was popular in films and novels during the 1920s, 1930s, and 1940s? Describe this Horror Trope thoroughly and identify examples of the trend. Why, during this time, were Mad Scientists the primary villains of the horror genre? In what ways did the Mad Scientist reflect cultural and religious anxieties of this time? Be specific.Describe the “New Modern Woman.” In what ways did she differ from her predecessors? What modern celebrities served as inspirations for the “New Modern Woman?” Why? In what ways did standards of female sexuality change during this era? Were there limits to this change? At what point did a “New Modern Woman’s” sense of liberation shift, change, or end?
