Sleep Late, a large hotel chain, has been using activity-based costing to determine the cost of a night’s stay at their hotels. One of the activities, “Inspection,” occurs after a customer has checked out of a hotel room. Sleep Late inspects every 10th room and has been using “number of rooms inspected” as the cost driver for inspection costs. A significant component of inspection costs is the cost of the supplies used in each inspection Mary Adams, the chief inspector, is wondering whether inspection labor-hours might be a better cost driver for inspection costs. Mary gathers information for weekly inspection costs, rooms inspected, and inspection labor-hours as follows: Q.Plot the data and regression line for rooms inspected and inspection costs. Plot the data and regression line for inspection labor-hours and inspection costs. Which cost driver of inspection costs would you choose? Explain.

Koontz Company manufactures a number of products. The standards relating to one of these products are shown below, along with actual cost data for May. Standard Cost per Unit Actual Cost per Unit Direct materials: Standard: 1.80 feet at $2.00 per foot Actual: 1.75 feet at $2.20 per foot Direct labor: Standard: 0.90 hours at $20.00 per hour Actual: 0.95 hours at $19.40 per hour Variable overhead: Standard: 0.90 hours at $6.40 per hour Actual: 0.95 hours at $6.00 per hour $ 3.60 $ 3.85 18.00 18.43 5.76 5.70 Total cost per unit $27.36 $27.98 Excess of actual cost over standard cost per unit $0.62 The production superintendent was pleased when he saw this report and commented: “This $0.62 excess cost is well within the 5 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product." Actual production for the month was 12,500 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were…
Accounting procedures allow a business to evaluate its inventory costs based on two methods: LIFO (last in first out) or FIFO (first in first out). A manufacturer evaluated its finished goods inventory (in $000s) for five products with the LIFO and FIIFO methods. To analyze the difference, they computed FIFO - LIFO for each product. We would like to determine if the LIFO method results in a lower cost of inventory than the FIFO method. The company wishes to test this hypothesis at the 0.05 level of significance.

use the given data on the societal cost of crashes and the approximate U.S. population of 325 million to calculate the average social cost per person. U.S. Data (2016 estimates): Car Crash fatalities = 40,200; Car Crash injuries = 4.6 million; cost to society = $430 billion. (source: National Safety Council.) • Global Data (estimated); car crash fatalities = ≈ 50 million; car crash fatalities with victim's underage 45 ≈ 400,000. (Source: Association Safe International Road Travel.) About how often (once every x minutes or x seconds) on average is a person killed in a car crash in the United States? How often is a person injured in a car crash.

The product design group of Iyengar Electric Supplies,Inc., has determined that it needs to design a new series of switches.It must decide on one of three design strategies. The market forecastis for 200,000 units. The better and more sophisticated the designstrategy and the more time spent on value engineering, the less willbe the variable cost. The chief of engineering design, Dr. W. L.Berry, has decided that the following costs are a good estimate of theinitial and variable costs connected with each of the three strategies:a) Low-tech: A low-technology, low-cost process consisting ofhiring several new junior engineers. This option has a fixedcost of $45,000 and variable-cost probabilities of .3 for $.55each, .4 for $.50, and .3 for $.45.b) Subcontract: A medium-cost approach using a good outsidedesign staff. This approach would have a fixed cost of $65,000and variable-cost probabilities of .7 of $.45, .2 of $.40, and .1 of $.35.c) High-tech: A high-technology approach using the very…
Private colleges and universities rely on money contributed by individuals and corporations for their operating expenses. Much of this money is invested in a fund called an endowment, and the college spends only the interest earned by the fund. A recent survey of five private colleges in the United States revealed the following endowments (in millions of dollars): 188.9, 249.3, 124.7, 157.6, and 222.8. What value will be used as the point estimate for the standard deviation of endowment of all private colleges in the United States? Round your answer to nearest hundredth(2d.p.) if necessary.
