Consider a remote town in which two restaurants, All-You-Can-Eat Cafe? and GoodGrub Diner, operate in a duopoly. Both restaurants disregard health and safety regulations, but they continue to have customers because they are the only restaurants within 80 miles of town. Both restaurants know that if they clean up, they will attract more customers, but this also means that they will have to pay workers to do the cleaning.
If neither restaurant cleans, each will earn $13,000; alternatively, if they both hire workers to clean, each will earn only $10,000. However, if one cleans and the other doesn't, more customers will choose the cleaner restaurant; the cleaner restaurant will make $18,000, and the other restaurant will make only $6,000.
If All-You-Can-Eat Cafe? and GoodGrub Diner decide to collude, the outcome of this game is as follows: All-You-Can-Eat Cafe? and GoodGrub Diner .
If both restaurants decide to cheat and behave noncooperatively, the outcome reflecting the unique Nash equilibrium of this game is as follows: All-You-Can-Eat Cafe? , and GoodGrub Diner .

R. Stichler et al. compared two methods of measuring treadwear in a paper. Eleven tires were each measured for treadwear by two methods: one based on weight, and the other on groove wear. The data, in thousands of miles, are in the table. Use the paired ?-test to answer the following: at the 5% significance level, do the data provide sufficient evidence to conclude that, on average, the two measurement methods give different results?
Weight Method ------------------- Groove Method -------------- Difference

| 30.9 | 25.9 | 5 |
| 31.9 | 23.3 | 8.6 |

A VLCC (very large crude carrier) is a large oil tanker that, when fully loaded, has a mass of 300,000 metric tons. (One metric ton is 1000 kg.) While several miles from port, the tanker is moving at a speed of 12.0 mph when the captain shuts dwn the engines. The tanker continues moving foward, slowed by the drag force of the water. After traweling a distance of 3.00 km the tanker's speed is 4.00 mph. Find the magnitude of the drag force against the tanker?

A US consumer lobby wishes to develop a model to predict gasoline usage, as measured by miles per gallon, based on the horsepower of the car's engine. The Excel data file AUTO.xls (contained in a folder under the CML Quizzes tab) contains data on this for fifty recent models. Use Excel Data Analysis to estimate a linear model for the relationship, a 92% confidence interval for the slope coefficient and the residual plot. State all numerical answers below correct to four decimal places using the Excel output results. 1. the intercept , 2. the slope coefficient , and 3. the standard error of the estimate, 4. Using this model, predict the gasoline mileage for the car with 120 horsepower. Use all decimal places in your calculation by selecting and using the values of b0 and b1 in the output generated by Excel. 5. Does the prediction involve extrapolating the relationship? Type yes or no. State the 6. lower bound 7. upper bound for the 92% confidence interval for the slope coefficient.
