In Boston, due to the large amount of snowfall during winter of
2014-2015, the city has brought in several "snow dragons" to melt
the snow.
Model SND5400 is rated at:
•180 ton rated capacity per hour (Based on Latent Heat of
Ice)
•No. 2 Fuel Oil or Diesel Fuel Type, Jet A Fuel
•Propane, and Natural Gas available for stationary units
•Fuel storage capacity of 3,000 US gallons
•Burner Output at 54,000,000 btu/hr
•Measures 68' long x 11'6" wide x 12'4" high
The USEPA states that there are 22,300 lb CO2 emitted
per 1000 gal of No. 2 fuel oil burned (AP-41 Table 1.3-12). The
heat content of No. 2 fuel oil is 140 MMBtu/103 gal
(AP-42 Chapter 1.3).
(a) How many lbs of CO2 are generated per hour when
operating at maximum capacity?
(b) Calculate the lbs of CO2 are generated per ton of
snow melted.
(c) If the snow has a density of 24.97 lb/ft3,
calculate the lbs of CO2 are generated per ft
3 of snow melted.
(d) If the snow is 78 inches deep, and the road is 30 ft in
width, calculate the lbs of CO2 that are generated in
clearing the snow from a length of road 10 ft.
(e) Based on the weighted average combined fuel economy of cars and light trucks in 2011, the amount of CO2 emitted per mile driven was 0.92594 lbs CO2/mile. Calculate the "equivalent miles" driven in clearing the snow from a length of road 10 ft (as in part (d)).

Several months ago, Ayers Industries Inc. experienced a hazardous materials spill at one of its plants. As a result, the Environmental Protection Agency (EPA) fined the company $430,000. The company is contesting the fine. In addition, an employee is seeking $540,000 in damages related to the spill. Lastly, a homeowner has sued the company for $270,000. The homeowner lives 30 miles from the plant, but believes that the incident has reduced the home's resale value by $270,000.
Ayers’ legal counsel believes that it is probable that the EPA fine will stand. In addition, counsel indicates that an out-of-court settlement of $230,000 has recently been reached with the employee. The final papers will be signed next week. Counsel believes that the homeowner's case is much weaker and will be decided in favor of Ayers. Other litigation related to the spill is possible, but the damage amounts are uncertain.
a. Journalize the contingent liabilities associated with the hazardous materials spill. Use the account "Damage Awards and Fines" to recognize the expense for the period. If an amount box does not require an entry, leave it blank.
b. The company experienced a hazardous materials spill at one of its plants during the previous period. This spill has resulted in a number of lawsuits to which the company is a party. The Environmental Protection Agency (EPA) has fined the company $, which the company is contesting in court. Although the company admit fault, legal counsel believes that the fine payment is . In addition, an employee has sued the company. A $ out-of-court settlement has been reached with the employee. The EPA fine and out-of-court settlement have been recognized as for the period. There is one other outstanding lawsuit related to this incident. Counsel believe that the lawsuit has merit. Other lawsuits and unknown liabilities may arise from this incident.

SecuriCorp operates a fleet of armored cars that make scheduled pickups and deliveries in the Los Angeles area. The company is implementing an activity-based costing system that has four activity cost pools: Travel, Pickup and Delivery, Customer Service, and Other. The activity measures are miles for the Travel cost pool, number of pickups and deliveries for the Pickup and Delivery cost pool, and number of customers for the Customer Service cost pool. The Other cost pool has no activity measure because it is an organization-sustaining activity. The following costs will be assigned using the activity-based costing system:
| Driver and guard wages | $ | 1,040,000 |
| Vehicle operating expense | 470,000 | |
| Vehicle depreciation | 350,000 | |
| Customer representative salaries and expenses | 380,000 | |
| Office expenses | 240,000 | |
| Administrative expenses | 540,000 | |
| Total cost | $ | 3,020,000 |
The distribution of resource consumption across the activity cost pools is as follows:
| Travel | Pickup and Delivery |

To illustrate the effects of driving under the influence of alcohol, a police officer brought a DUI simulator to a local high school. Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine teenagers, the time (in seconds) required to bring the vehicle to a stop from a speed of 60 miles per hour was recorded. Complete parts (a) and (b). Note: A normal probability plot and boxplot of the data indicate that the differences are appromixately normally distributed with no outliers.
| Subject | Normal, X1 | Impaired, Y1 |
|---|---|---|
| 1 | 4.47 | 5.77 |
| 2 | 4.24 | 5.85 |
| 3 | 4.58 | 5.45 |
| 4 | 4.65 | 5.32 |
| 5 | 4.31 | 5.90 |
| 6 | 4.83 | 5.49 |
| 7 | 4.55 | 5.23 |
| 8 | 5.00 | 5.61 |
| 9 | 4.79 | 5.63 |
(a) Whether the student had unimpaired vision or wore goggles first was randomly selected. Why is this a good idea in designing the experiment?
A)This is a good idea in designing the experiment because it
controls for any "learning" that may occur in using the
simulator.
B)This is a good idea in designing the experiment because reaction times are different
C) This is a good idea in designing the experiment because the
sample size is not large enough
(b) Use a 95% confidence interval to test if there is a difference in braking time with impaired vision and normal vision where the differences are computed as "impaired minus normal"
The lower bound is ______
The upper bound is _______
(Round to the nearest thousandth as needed)
State the appropriate conclusion
A)There is sufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision
B)There is insufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision

| Suppose a tour agent approached the general manager of the Grand Canyon Railway with a proposal to offer a special guided tour to the agent’s clients. | ||||||||
| The tour would occur 20 times each summer and be part of a larger itinerary that the agent is putting together. The agent presented two options: | ||||||||
| (a) a special 65-mile tour with the agent’s 30 clients as the only passengers on the train, or | ||||||||
| (b) adding a car to an existing train to accommodate the 30 clients on an already scheduled 65-mile tour. | ||||||||
| Under either option, Grand Canyon would hire a tour guide for $200 for the trip. Grand Canyon has extra cars in its switching yard, and it would cost $40 | ||||||||
| to move a car to the main track and hook it up. The extra fuel cost to pull one extra car is $.20 per mile. To run an engine and a passenger car on the trip | ||||||||
| would cost $2.20 per mile, and an engineer would be paid $400 for the trip. | ||||||||
| Depreciation on passenger cars is $5,000 per year, and depreciation on engines is $20,000 per year. Each passenger car and each engine travels about | ||||||||
| 50,000 miles a year. They are replaced every 8 years. | ||||||||
|
The agent offered to pay $32 per passenger for the special tour and $15 per passenger for simply adding an extra car. Assume you are the tour guide. What questions do you have about the way your proposal was analyzed? What changes might you make to your proposal to make it more appealing? In what ways do you see applying the approach taken in for the Grand Canyon Railways analysis to other situations? |

. The first job offer is close to your parents’ house (they live in Winnetka which is 16 miles north of downtown Chicago). Your parents have offered to let you live at home for a year so you won’t have to incur expenses for housing, food, or cable and internet. This job pays $45,000 per year. The second job is far from your parents’ house, but close to downtown Chicago. However, you will have to rent a studio apartment with parking ($9,000 per year), buy your own food ($2,000 per year), and pay for your own cable and internet ($800 per year). This job pays $52,000 per year. You still plan to do laundry at your parents’ house once a week if you live in the city, and you plan to go into the city once a week to visit with friends if you live at home. Thus, the cost of operating a car will be about the same either way. In addition, your parents refuse to pay for your cell phone service ($680 per year) no matter which job offer you choose to accept. Requirements: 1. Based on the information provided above, what is the net difference between the two alternatives (salary, net of relevant costs)? (Worth 3 pts.) 2. What information is irrelevant? Why? (Worth 2 pts.) 3. What qualitative factors or information is relevant to your decision? (Worth 3 pts.) 4. Assume that you really want to take Job #2, what other quantitative and qualitative information will you need to incorporate into your decision beyond the costs originally listed? (Worth 5 pts.)
