Chapter 3, Problem 6CE
The controller for Dohini Manufacturing Company felt that the number of purchase orders alone did not explain the monthly purchasing cost. He knew that nonstandard orders (for example, one requiring an overseas supplier) took more time and effort. He collected data on the number of nonstandard orders for the past 12 months and added that information to the data on purchasing cost and total number of purchase orders.
Multiple regression was run on the above data; the coefficients shown by the regression program are:
Required:
- 1. Construct the cost formula for the purchasing activity showing the fixed cost and the variable rate.
- 2. If Dohini Manufacturing Company estimates that next month will have 430 total purchase orders and 45 nonstandard orders, what is the total estimated purchasing cost for that month? (Round your answer to the nearest dollar.)
- 3. What if Dohini Manufacturing wants to estimate purchasing cost for the coming year and expects 5,340 purchase orders and 580 nonstandard orders? What will estimated total purchasing cost be? What is the total fixed purchasing cost? Why doesn’t it equal the fixed cost calculated in Requirement 2? (Round your answers to the nearest dollar.)

- The 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_forwardAssume you have asked your data folks to determine the relationship between customer service scores (i.e. the ratings provided by customers in response to a survey) and profit. The analyst reports the following: "I gathered data for the last 48 months and ran a regression where profit in a given month is the dependent variable and customer service score in that same month is the independent variable. I found an intercept of $10,000 (p-value: 0.31) and the coefficient on customer service score is $1,200 (p-value: 0.22). The R-2 (which is appropriate when there is just one independent variable) is 0.07."

The company has the following performance metrics on its balanced scorecard: days from ordered to delivered, number of shipping errors, customer retention rate, nd market share. A measure map illustrates that the days from ordered to delivered and the number of shipping errors are both expected to directly affect the customer retention rate, which affects market share. Additional internal analysis finds that: Every shipping error over three shipping errors per month reduces the customer retention rate by 1.5%. On average, each day above three days from ordered to delivered yields a reduction in the customer retention rate of 1%. Each day before three days from order to delivery yields an increase in the customer retention rate of 1%, on average. Rizzo Goal Inc.'s current customer retention rate is 60%.

Ignoring any other factors, if the company has six shipping errors this month and an average of 3.5 days from ordered to delivered, determine (a) the new customer retention rate and (b) the new market share that Rizzo Goal Inc. expects to have.arrow_forwardDeMarco Company is developing a cost formula for its packing activity. Discussion with the workers in the Packing Department has revealed that packing costs are associated with the number of customer orders, the size of the orders, and the relative fragility of the items (more fragile items must be specially wrapped in bubble wrap and Styrofoam). Data for the past 20 months have been gathered: Required: 1. Using the method of least squares, run a regression using the number of orders as the independent variable. 2. Run a multiple regression using three independent variables: the number of orders, the weight of orders, and the number of fragile items. Which regression equation is better? Why? 3. Predict the total packing cost for 25,000 orders, weighing 40,000 pounds, with 4,000 fragile items.arrow_forward
- In a manufacturing process the assembly line speed (feet per minute) was thought to affect the number of defective parts found during the inspection process. To test this theory, managers devised a situation in which the same batch of parts was inspected visually at a variety of line speeds. They collected the following data: Develop a scatter chart with line speed as the independent variable. What does the scatter chart indicate about the relationship between line speed and the number of defective parts found? Use the data to develop an estimated regression equation that could be used to predict the number of defective parts found, given the line speed. 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 number of defective parts found for the sample data does the model you estimated in part (b) explain?arrow_forwardRefer 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_forwardA marketing professor at Givens College is interested in the relationship between hours spent studying and total points earned in a course. Data collected on 156 students who took the course last semester are provided in the tile MktHrsPts. Develop a scatter chart for these data.
