- Refer to the information for Farnsworth Company (p. 139) for the first 10 months of data on receiving orders and receiving cost. Now suppose that Tracy has gathered 2 more months of data: Note: For the following requirements, round the intercept terms to the nearest dollar, round the variable rates to the nearest cent, and R2 to two decimal places. Required: 1. Run two regressions using a computer spreadsheet program such as Excel. First, use the method of least squares on the first 10 months of data. Then, use the method of least squares on all 12 months of data. Write down the results for the intercept, slope, and R2 for each regression. Compare the results. 2. CONCEPTUAL CONNECTION Prepare a scattergraph using all 12 months of data. Do any points appear to be outliers? Suppose Tracy has learned that the factory suffered severe storm damage during Month 11 that required extensive repairs to the receiving areaincluding major repairs on a forklift. These expenses, included in Month 11 receiving costs, are not expected to recur. What step might Tracy, using her judgment, take to amend the results from the method of least squares? 3. CONCEPTUAL CONNECTION Rerun the method of least squares, using all the data except for Month 11. (You should now have 11 months of data.) Prepare a cost formula for receiving based on these results, and calculate the predicted receiving cost for a month with 1,450 receiving orders. Discuss the results from this regression versus those from the regression for 12 months of data.arrow_forwardThe Lockit Company manufactures door knobs for residential homes and apartments. Lockit is considering the use of simple (single-driver) and multiple regression analyses to forecast annual sales because previous forecasts have been inaccurate. The new sales forecast will be used to initiate the budgeting process and to identify more completely the underlying process that generates sales. Larry Husky, the controller of Lockit, has considered many possible independent variables and equations to predict sales and has narrowed his choices to four equations. Husky used annual observations from 20 prior years to estimate each of the four equations. Following are definitions of the variables used in the four equations and a statistical summary of these equations: St=ForecastedsalesindollarsforLockitinperiodtSt1=ActualsalesindollarsforLockitinperiodt1Gt=ForecastedU.S.grossdomesticproductinperiodtGt1=ActualU.S.grossdomesticproductinperiodt1Nt1=Lockitsnetincomeinperiodt1 Required: 1. Write Equations 2 and 4 in the form Y = a + bx. 2. If actual sales are 1,500,000 in the current year, what would be the forecasted sales for Lockit in the coming year? 3. Explain why Larry Husky might prefer Equation 3 to Equation 2. 4. Explain the advantages and disadvantages of using Equation 4 to forecast sales.arrow_forwardCooper Realty is a small real estate company located in Albany, New York, that specializes primarily in residential listings. The company recently became interested in determining the likelihood of one of its listings being sold within a certain number of days. An analysis of company sales of 800 homes in previous years produced the following data. a. If A is defined as the event that a home is listed for more than 90 days before being sold, estimate the probability of A. b. If B is defined as the event that the initial asking price is under 150,000, estimate the probability of B. c. What is the probability of AB? d. Assuming that a contract was just signed to list a home with an initial asking price of less than 150,000, what is the probability that the home will take Cooper Realty more than 90 days to sell? e. Are events A and B independent?arrow_forward
