Motorcycle-safety courses, offered by a number of organizations, teach motorcyclists important techniques for handling their vehicles and for safely sharing the road with other road users. if more motorcyclists took these courses, there would be fewer serious motorcycle accidents. data show that 92 percent of the motorcyclists who are involved in a serious motorcycle accident have never taken a motorcycle-safety course. in assessing whether the data cited provide support for the position taken about more motorcyclists’ taking the courses, it would be most useful to determine which of the following? (a) whether significantly more than eight percent of motorcyclists have taken a motorcycle-safety course
(b ) whether it is riskier for a motorcyclist to ride with a passenger behind the rider than to ride alone
(c) whether the different organizations that offer motorcycle-safety courses differ in the content of the courses that they offer
(d) whether more than 92% of serious motorcycle accidents involve collisions between a motorcycle and another vehicle in motion.
(e) whether variations in the size and potential speed of a motorcycle influence the risk of a serious accident's occuring.

Blue computers, a major pc manufacturer in the united states, currently has plants in kentucky and pennsylvania. the kentucky plant has a capacity of 1 million units a year and the pennsylvania plant has a capacity of 1.5 million units a year. the firm divides the united states into five markets: northeast, southeast, midwest, south, and west. each pc sells for $1,000. the firm anticipates a 50 perc~nt growth in demand (in each region) this year (after which demand will stabilize) and wants to build a plant with a capacity of 1.5 million units per year to accommodate the growth. potential sites being considered are in north carolina and california. currently the firm pays federal, state, and local taxes on the income from each plant. federal taxes are 20 percent of income, and all state and local taxes are 7 percent of income in each state. north carolina has offered to reduce taxes for the next 10 years from 7 percent to 2 percent. blue computers would like to take the tax break into consideration when planning its network. consider income over the next 10 years in your analysis. assume that all costs remain unchanged over the 10 years. use a discount factor of 0.1 for your analysis. annual fixed costs, production and shipping costs per unit, and current regional demand (before the 50 percent growth) are shown in table 5-13. (a) if blue computers sets an objective of minimizing total fixed and variable costs, where should they build the new plant? how should the network be structured? (b) if blue computers sets an objective of maximizing after-tax profits, where should they build the new plant? how should the network be structured? variable production and shipping cost ($/unit) annual fixed cost northeast southeast midwest south west (million$) kentucky 185 180 175 175 200 150 pennsylvania 170 190 180 200 220 200 n. carolina 180 180 185 185 215 150 california 220 220 195 195 175 150 demand ('000 units/month) 700 400 400 300 600
