The stock price of company x doubled over the past year, the stock price of company z decreased by over 50%. if the market is efficient, if the stocks have the same beta, and if you do a little research: a. will you be able to identify which stock is most likely to have the higher actual investment return next year? why or why not? b. will you be able to identify the economic factors that contributed to last year's stock returns? (i. e., why did company x double, and why did company z decrease by 50%? ) why or why not?

This exercise illustrates that poor quality can affect schedules and costs. a manufacturing process has 130 customer orders to fill. each order requires one component part that is purchased from a supplier. however, typically, 3% of the components are identified as defective, and the components can be assumed to be independent. (a) if the manufacturer stocks 130 components, what is the probability that the 130 orders can be filled without reordering components? (b) if the manufacturer stocks 132 components, what is the probability that the 130 orders can be filled without reordering components? (c) if the manufacturer stocks 135 components, what is the probability that the 130 orders can be filled without reordering components?
