Q. Table gives data on gold prices, the Consumer Price Index (CPI), and the New York Stock Exchange (NYSE) Index for the United States for the period 1974 –2006. The NYSE Index includes most of the stocks listed on the NYSE, some 1500-plus.
a. Plot in the same scattergram gold prices, CPI, and the NYSE Index.
b. An investment is supposed to be a hedge against inflation if its price and /or rate of return at least keeps pace with inflation. To test this hypothesis, suppose you decide to fit the following model, assuming the scatterplot in (a) suggests that this is appropriate:
Gold pricet = β1 + β2 CPIt + ut
NYSE indext = β1 + β2 CPIt + ut
Note that if beta2 = 1 the response exactly grows with CPI

2.62 For the period 2001–2008, the Bristol-Myers Squibb Company, Inc. reported the following amounts (in billions of dollars) for (1) net sales and (2) advertising and product promotion. The data are also in the file XR02062.
Source: Bristol-Myers Squibb Company, Annual Reports, 2005, 2008.
Year Net Sales Advertising/Promotion
2001 $16.612 $1.201
2002 16.208 1.143
2003 18.653 1.416
2004 19.380 1.411
2005 19.207 1.476
2006 16.208 1.304
2007 18.193 1.415
2008 20.597 1.550
For these data, construct a line graph that shows both net sales and expenditures for advertising/product promotion over time. Some would suggest that increases in advertising should be accompanied by increases in sales. Does your line graph support this?

- A shoe company forecasts the following demands during the next six months: month 1 – 200; month 2 – 260; month 3 – 240; month 4 – 340; month 5 – 190; month 6 – 150. It costs $7 to produce a pair of shoes with regular-time labor and $11 with overtime labor. During each month, regular production is limited to 200 pairs of shoes, and overtime production is limited to 100 pairs. It costs $1 per month to hold a pair of shoes in inventory. The initial inventory is 0. Let xi = pairs of shoes produced in month i using regular-time labor, yi = pairs of shoes produced in month i using overtime labor, and zi = inventory of shoes at the end of month i. Using these decision variables, formulate an LP that minimizes the total cost and meets the demand on time in the next six months.arrow_forwardThe Toro Cutlery Company has collected monthly sales information below!
