A) The physical plant at the main campus of a large state
university recieves daily requests to replace florecent lightbulbs.
The distribution of the number of daily requests is bell-shaped and
has a mean of 45 and a standard deviation of 4. Using the
68-95-99.7 rule, what is the approximate percentage of lightbulb
replacement requests numbering between 45 and 57?
B) A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 45 months and a standard deviation of 3 months. Using the 68-95-99.7 rule, what is the approximate percentage of cars that remain in service between 36 and 39 months?
C) The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has a bell-shaped distribution. This distribution has a mean of 60 and a standard deviation of 8. Using the empirical rule, what is the approximate percentage of 1-mile long roadways with potholes numbering between 36 and 76?

c.) Predict the number of days absent for an employee who lives 5 miles from the hospital
d.) Write the regression equation

Calculate the contribution per mile and total annual contribution associated with accepting FHP's proposal. What do you recommend? (Use 52 weeks per year in your calculations.)
Consider the strategic implications (including risks) associated with expanding (or choosing not to expand) operations to meet the demands ofFHP. Analyze this question from a conceptual point of view. Calculations are not necessary.
After a closer examination of capacity, management believes an additional rig is required to service the FHP account. Assume Cascade's management chooses to invest in one additional truck and trailer that can serve the needs of FHP (at least initially). Assume the annual incremental fixed costs associated with acquiring the additional equipment is $50,000. Further, FHP would agree to pay $2.20 per mile (total including FSC and miscellaneous) if Cascade would sign a five-year contract. What is the annual number of miles required for Cascade to break even, assuming the company adds one truck and trailer?
What is the expected annual increase in profitability from the FHP contract? (Use 52 weeks per year in your calculations.)

Can a low barometer reading be used to predict maximum wind speed of an approaching tropical cyclone? For a random sample of tropical cyclones, let x be the lowest pressure (in millibars) as a cyclone approaches, and let y be the maximum wind speed (in miles per hour) of the cyclone.
| x | 1004 | 975 | 992 | 935 | 982 | 924 |
| y | 40 | 100 | 65 | 145 | 68 | 153 |
Use a calculator to verify that Σx = 5812,
Σx2 = 5,635,030, Σy = 571,
Σy2 = 64,883 and Σxy = 545,863.
Compute r. (Round to 3 decimal places.)
As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer.
Given our value of r, y should tend to increase as x increases.
Given our value of r, y should tend to decrease as x increases.
Given our value of r, y should tend to remain constant as x increases.
Given our value of r, we can not draw any conclusions for the behavior of y as x increases.

The cost of the pipeline and the cost of pumping the water will vary with pipe size. See table below. The contractor uses a MARR of 7%. The contractor plans to work 2000 hours per year, and that is the time the pump will run each year.

Cheshire Plants is delivering the monthly supply of their fine product to their seven customers. The distances in miles between the customers are shown in the table and, wishing to be as efficient as possible, the driver would like to find the shortest route that takes her from the starting point A to every customer and then back to the starting point. Use the nearest neighbor heuristic to identify a route that would minimize the distance traveled. Show work

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 $240,000. The company is contesting the fine. In addition, an employee is seeking $220,000 in damages related to the spill. Lastly, a homeowner has sued the company for $310,000. The homeowner lives 35 miles from the plant but believes that the incident has reduced the home’s resale value by $310,000.
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 $125,000 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.
| Required: | |
| A. | On December 31, journalize the contingent liabilities associated with the hazardous materials spill. Use the account “Damage Awards and Fines” to recognize the expense for the period. Refer to the Chart of Accounts for exact wording of account titles. |
| B. | Prepare a note disclosure relating to this incident. |
