Baseball has always been a favorite pastime in America and is rife with statistics and theories. In a paper, researchers showed that major league players who have nicknames live an average of 2½ years longer than those without them (The Wall Street Journal, July 16, 2009). You do not believe in this result and decide to collect data on the lifespan of 30 baseball players along with a nickname variable that equals 1 if the player had a nickname and 0 otherwise. The data are shown in the accompanying table and are contained in the accompanying Excel file. (You may find it useful to reference the appropriate table: z table or t table) Years Nickname Years Nickname Years Nickname 74 1 61 0 68 1 62 1 64 0 68 0 67 1 70 0 64 1 73 1 71 1 67 1 49 1 69 1 64 0 62 0 56 0 63 1 56 0 68 1 68 1 63 0 70 1 68 1 80 1 79 1 74 0 65 1 67 0 64 0 Click here for the Excel Data File Let Samples 1 and 2 represent…

Price elasticity of demand (supply) or simply elasticity of demand (supply) measures the relative or percentage variation experienced by the quantity demanded (supplied) as a consequence of a change in the price of one percent (1%); In other words, it measures the intensity with which buyers (sellers) respond to a change in the priceprice. Elasticity is often used with respect to the price-demand relationship or the price-supply relationship, but the applicability of this concept is not restricted to that single case, but is broader, since the elasticity is calculated in percentages, since it is the only way to obtain a common unit of measure. When calculating the elasticity in arelationship, the units of measurement are maintained, therefore, they do not measure a proportional change, but a propensity, such as the well-known propensit to Keynesian consumption. The rate at which the selling price changes and from a product, with respect to its supply "x", is given by the following…
Canton Supplies, Inc., is a service firm that employs approximately 100 people. Because of the necessity of meeting monthly cash obligations, the chief financial officer wants to develop a forecast of monthly cash requirements. Because of a recent change in equipment and operating policy, only the past seven months of data are considered relevant. The change in operations has had a great impact on cash flow. What forecasting model do you recommend? Use the Moving Average and Exponential Smoothing Excel templates or other Excel tools to help you answer this question.

Describe the results of your two graphs as they compare to the movement of demand. Be specific. Choosing between the three-period and the five-period forecasts, which length of averaging would you use as a purchasing manager of Greenfield’s Tannery? Be sure to factor in the cumulative forecast errors in your answer. Also, make sure you include some rationale about why you are picking the method you do for this particular business. So for example, does picking one method over the other have any impact on how much inventory they will have on hand to meet customer demand? What happens when the demand drops? Which method better supports that?
