Required
1. Prepare a scattergraph using the data given above. Plot cost on the vertical axis and activity on the horizontal axis. Is there an approximately linear relationship between shipping expense and the number of units shipped?
2. Using the high-low method, estimate the cost formula for shipping expense. Draw a straight line through the high and low data points shown in the scattergraph that von prepared in requirement (1). Make sure vow line intersects the Y-axis.
3. Comment on the accuracy of vow high-low estimates assuming a least-squares regression analysis estimated the total fixed costs to be $91071 per month and the variable cost to be $217.86 per unit. How would the straight line that yon drew in requirement 2 differ from a straight line that minimizes the sum of the squared errors?
4. What factors, other than the number of units shipped, are likely to affect the company's shipping expense? Explain.

- Patterson Company produces wafers for integrated circuits. Data for the most recent year are provided: aCalculated using number of dies as the single unit-level driver. bCalculated by multiplying the consumption ratio of each product by the cost of each activity. Required: 1. Using the five most expensive activities, calculate the overhead cost assigned to each product. Assume that the costs of the other activities are assigned in proportion to the cost of the five activities. 2. Calculate the error relative to the fully specified ABC product cost and comment on the outcome. 3. What if activities 1, 2, 5, and 8 each had a cost of 650,000 and the remaining activities had a cost of 50,000? Calculate the cost assigned to Wafer A by a fully specified ABC system and then by an approximately relevant ABC approach. Comment on the implications for the approximately relevant approach.arrow_forwardBig Mikes, a large hardware store, has gathered data on its overhead activities and associated costs for the past 10 months. Nizam Sanjay, a member of the controllers department, believes that overhead activities and costs should be classified into groups that have the same driver. He has decided that unloading incoming goods, counting goods, and inspecting goods can be grouped together as a more general receiving activity, since these three activities are all driven by the number of receiving orders. The 10 months of data shown below have been gathered for the receiving activity. Required: 1. Prepare a scattergraph, plotting the receiving costs against the number of purchase orders. Use the vertical axis for costs and the horizontal axis for orders. 2. Select two points that make the best fit, and compute a cost formula for receiving costs. 3. Using the high-low method, prepare a cost formula for the receiving activity. 4. Using the method of least squares, prepare a cost formula for the receiving activity. What is the coefficient of determination?arrow_forwardScattergraph, High-Low Method, and Predicting Cost for a Different Time Period from the One Used to Develop a Cost Formula Refer to the information for Farnsworth Company on the previous page. Required: 1. Prepare a scattergraph based on the 10 months of data. Does the relationship appear to be linear? 2. Using the high-low method, prepare a cost formula for the receiving activity. Using this formula, what is the predicted cost of receiving for a month in which 1,450 receiving orders are processed? 3. Prepare a cost formula for the receiving activity for a quarter. Based on this formula, what is the predicted cost of receiving for a quarter in which 4,650 receiving orders are anticipated? Prepare a cost formula for the receiving activity for a year. Based on this formula, what is the predicted cost of receiving for a year in which 18,000 receiving orders are anticipated? Use the following information for Problems 3-60 and 3-61: Farnsworth Company has gathered data on its overhead activities and associated costs for the past 10 months. Tracy Heppler, a member of the controllers department, has convinced management that overhead costs can be better estimated and controlled if the fixed and variable components of each overhead activity are known. One such activity is receiving raw materials (unloading incoming goods, counting goods, and inspecting goods), which she believes is driven by the number of receiving orders. Ten months of data have been gathered for the receiving activity and are as follows:arrow_forward
- Morrison Company had the equivalent units schedule and cost information for its Sewing Department for the month of December, as shown on the next page. Required: 1. Calculate the unit cost for December, using the weighted average method. 2. Calculate the cost of goods transferred out, calculate the cost of EWIP, and reconcile the costs assigned with the costs to account for. 3. What if you were asked to show that the weighted average unit cost for materials is the blend of the November unit materials cost and the December unit materials cost? The November unit materials cost is 6.60 (66,000/10,000), and the December unit materials cost is 12.22 (550,000/45,000). The equivalent units in BWIP are 10,000, and the FIFO equivalent units are 45,000. Calculate the weighted average unit materials cost using weights defined as the proportion of total units completed from each source (BWIP output and current output).arrow_forwardLarsen, Inc., produces two types of electronic parts and has provided the following data: There are four activities: machining, setting up, testing, and purchasing. Required: 1. Calculate the activity consumption ratios for each product. 2. Calculate the consumption ratios for the plantwide rate (direct labor hours). When compared with the activity ratios, what can you say about the relative accuracy of a plantwide rate? Which product is undercosted? 3. What if the machine hours were used for the plantwide rate? Would this remove the cost distortion of a plantwide rate?arrow_forwardGunnison Company had the following equivalent units schedule and cost information for its Sewing Department for the month of December: Required: 1. Calculate the unit cost for December, using the FIFO method. 2. Calculate the cost of goods transferred out, calculate the cost of EWIP, and reconcile the costs assigned with the costs to account for. 3. What if you were asked for the unit cost from the month of November? Calculate Novembers unit cost and explain why this might be of interest to management.arrow_forward
- This information was collected for the first year of manufacturing for Appliance Apps: Prepare an income statement under variable costing, and prepare a reconciliation to the income under the absorption method.arrow_forwardCarolina Yachts builds custom yachts in its production factory in South Carolina. Once complete, these yachts must be shipped to the dealership. They have collected this shipping cost data: Prepare a scatter graph of the shipping data. Plot cost on the vertical axis and yachts shipped on the horizontal axis. Is the relationship between shipping costs and unit shipped approximately linear? Draw a straight line through the scatter graph. Using the high-low method, create the cost formula for Carolina Yachts shipping costs. The least-squares regression method was used and the analysis resulted in this cost equation: Y= 4,000+ 1,275x. Comment on the accuracy of your high-low method estimation. What would you estimate shipping costs to be if Carolina Yachts shipped 10 yachts in a single month? Use the cost formula you obtained in part B. Comment on how accurately this is reflected by the scatter graph you constructed. What factors other than number of yachts shipped do you think could affect Carolina Yachts shipping expense? Explain.arrow_forwardSilven Company has identified the following overhead activities, costs, and activity drivers for the coming year: Silven produces two models of cell phones with the following expected activity demands: 1. Determine the total overhead assigned to each product using the four activity drivers. 2. Determine the total overhead assigned to each model using the two most expensive activities. The costs of the two relatively inexpensive activities are allocated to the two expensive activities in proportion to their costs. 3. Using ABC as the benchmark, calculate the percentage error and comment on the accuracy of the reduced system. Explain why this approach may be desirable.arrow_forward
