10. Now assume the same information: The Beach Bum Surf Co. is evaluating the inventory of its most popular boogie board as the summer season ends. They had beginning inventory of 20 boards at a cost of $25. Then purchases of 130 boards at $27 each, 140 boards at $28 each, and 135 boards at $30 each. If ending inventory is 15 boards and Beach Bum uses the average cost method, what would be the dollar amount assigned to cost of goods sold?

According to the National Automobile Dealers Association, the mean price for used cars is 10,192. A manager of a Kansas City used car dealership reviewed a sample of 50 recent used car sales at the dealership in an attempt to determine whether the population mean price for used cars at this particular dealership differed from the national mean. The prices for the sample of 50 cars are shown in the tile named UsedCars. a. Formulate the hypotheses that can be used to determine whether a difference exists in the mean price for used cars at the dealership. b. What is the p value? c. At = 0.05, what is your conclusion?

The Toyota Camry is one of the best-selling cars in North America. The cost of a previously owned Camry depends on many factors, including the model year, mileage, and condition. To investigate the relationship between the car’s mileage and the sales price for Camrys, the following data show the mileage and sale price for 19 sales (PriceHub web site, February 24, 2012). Develop a scatter chart for these data with miles as the independent variable. What does the scatter chart indicate about the relationship between price and miles? Develop an estimated regression equation showing how price is related to miles. What is the estimated regression model? Test whether each of the regression parameters β0 and β1 is equal to zero at a 0.01 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable? How much of the variation in the sample values of price does the model estimated in part (b) explain? For the model estimated in part (b), calculate the predicted price and residual for each automobile in the data. Identify the two automobiles that were the biggest bargains. Suppose that you are considering purchasing a previously owned Camry that has been driven 60.000 miles. Use the estimated regression equation developed in part (b) to predict the price for this car. Is this the price you would offer the seller?
