A researcher believes that 8% of pet dogs in Europe are Labradors. If the researcher is right, what is the probability that the proportion of Labradors in a sample of 630 pet dogs would be greater than 7%? Round your answer to four decimal places.

My question is since the z table is 0.925 would I add up both scores and then divide by two? Or would I just round up?

Problem #3

Company needs to decide between two machines.

Machine C costs 10,000 and produce after tax cash flows of 4,000 per year for 3 years. No salvage.

Machine D costs 14,000 and produce after tax cash flows of 3,000 per year for 7 years. No salvage.

Discount rate is 8%

Which machine would you recommend?

The reservation office for Central Airlines has two agents answering incoming phone calls for flight reservations....

The reservation office for Central Airlines has two agents answering incoming phone calls for flight reservations. A caller can be put on hold until one of the agents is available to take the call. If all three phone lines (both agent lines and the hold line) are busy, a potential customer gets a busy signal, in which case the call is lost. All calls occur randomly (i.e., according to a Poisson process) at a mean rate of 15 per hour. The length of a telephone conversation has an exponential distribution with a mean of 4 minutes.

(a)Construct the rate diagram for this queueing system.

(b) Find the steady-state probability that:

(i) A caller will get to talk to an agent immediately.

(ii) The caller will be put on hold, and

(iii) The caller will get a busy signal.

Black Mountain Ski Resort has been granted a 20 - year permit to develop and operate...

Black Mountain Ski Resort has been granted a 20 - year permit to develop and operate a skiing operation in a national park. After 20 years the site must be returned to its original condition. The roads may remain, as they can be used for fire prevention purposes. In the spring and summer before the ski hill opened, the following transactions and events occurred:

You must use the following Long-Lived asset accounts

Ski Lift

Ski Chalet

Land improvement

Roads

Parking lot

  1. Installed three ski lifts for a total cost of $150,000,000. It is estimated that the scrap metal from the lifts could be sold for $4,000,000 at the end of 20 years.
  2. Built a Ski chalet for $70,000,000
  3. Removed Trees and cleared the area for ski runs at a cost of $40,000,000
  4. Received $ 10,000,000 for the trees that were removed for the ski runs.
  5. Put in roads for a cost of $50,000,000.
  6. Paved an area at the base of the mountain for a parking lot at a cost of $10,000,000.
  7. Estimated that it would cost $20,000,000 to dismantle the ski lifts in 20 years. The chalet could be removed for a cost of $15,000,000. Re-foresting the site would cost $5,000,000. Removing the parking lot will cost $3,000,000. Calculate the PV of Site Restoration using a risk rate of 6% and provide the journal entry.
  8. Using Straight Line Depreciation record the depreciation for the first year of operations on the Long-Lived assets and site restoration costs. Put all the depreciation expense in one account and then create accumulated depreciation accounts for each asset that requires depreciation.

  9. Allocate the interest expense on the site restoration costs for the first three years

  10. Using the table below prepare the balance sheet presentation of all the accounts involved in this question for the end of the third year of operations.
