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
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:
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.

- Valencia Products make automobile radar detectors and assembles two models: LaserStop and SpeedBuster. Both models use the same electronic components. After reviewing the components required and the profit for each model, the firm found the following linear optimization model for profit, where x is the number of LaserStop models produced and y is the number of SpeedBuster models produced. Graph the constraints and identify the feasible region. Then identify each of the corner points and show how increasing the objective function value identifies the optimal solution.

Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). a. Develop a scatter chart with weekly usage hours as the independent variable. What does the scatter chart indicate about the relationship between weekly usage and annual maintenance expense? b. Use the data to develop an estimated regression equation that could be used to predict the annual maintenance expense for a given number of hours of weekly usage. What is the estimated regression model? c. Test whether each of the regression parameters 0 and 1 is equal to zero at a 0.05 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable? d. How much of the variation in the sample values of annual maintenance expense does the model you estimated in part (b) explain? e. If the maintenance contract costs 3,000 per year, would you recommend purchasing it? Why or why not?arrow_forwardSuppose that Demont has been given a summer job as an intern at Isaac Aircams, a company that manufactures sophisticated spy cameras for remote-controlled military reconnaissance aircraft.

- Price and efficiency variances, benchmarking and ethics. Sunto Scientic manufactures GPS devices for a chain of retail stores. Its most popular model, the Magellan XS, is assembled in a dedicated facility in Savannah, Georgia. Sunto is keenly aware of the competitive threat from smartphones that use Google Maps and has put in a standard cost system to manage production of the Magellan XS. It has also implemented a just-in-time system so the Savannah facility operates with no inventory of any kind. Producing the Magellan XS involves combining a navigation system (imported from Sunto’s plant in Dresden at a xed price), an LCD screen made of polarized glass, and a casing developed from specialty plastic.The budgeted and actual amounts for Magellan XS for July 2017 were as follows:arrow_forwardizzo Goal Inc. produces and sells hockey equipment, often custom made for online orders. 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%.

With this in mind, she instructs several staff members to investigate this prospective product further, including developing estimates of the related costs and revenues as well as forecasting the potential sales. One month later, the preliminary estimates of the relevant financial figures come back. The cost of designing the grandfather clock and then setting up the production facilities to produce this product would be approximately $250,000. There would be only one production run for this limited-edition grandfather clock. The additional cost for each clock produced would be roughly $2,000. The marketing department estimates that their price for selling the clocks can be successfully set at about $4,500 apiece, but a firm forecast of how many clocks can be sold at this price has not yet been obtained. However, it is…arrow_forward
