Q2d13A
After successfully “pitching” his project to management, Angus MacDonald has started to collect the data needed to build his model. Angus first order of business is to collect data on shipping times for steel shipment between Nanticoke, ON and Halifax, NS. To estimate this time, Angus has obtained transit times from two shipping firms (A & B) that currently ship oil between refineries in Nanticoke and Dartmouth, NS. (Dartmouth is located across the harbor from Halifax). Each firm reported its shipping time in days for its last 10 deliveries:
A B
| 10 | 8 |
| 8 | 9 |
| 10 | 7 |
| 2 | 18 |
| 11 | 8 |
| 8 | 12 |
| 6 | 4 |
| 11 | 5 |
| 11 | 6 |
| 9 | 11 |
a. Assuming transit times between the two ports to be normally distributed, determine if the 4th data entry for Firm A (2 days) can be considered to be an anomaly.
b. Considering only shipping Firm B, how many data samples will Angus need to collect to ensure that he can obtain an estimates for transit time that is within ±1 day 19 times out of 20?
c. Based on the results from this pilot study, which of the two firms should be selected as to deliver steel to Halifax? State any assumption that you make and justify your results.
d. Assume Angus collect 100 data points from Firm B only and obtains the following histogram:
|
Shipping Time |
Count |
|
0 – 4.999 |
10 |
|
5 – 9.999 |
40 |
|
10 – 14.999 |
30 |
|
15 – 19.999 |
8 |
| 20+ | 12 |
Angus hypothesizes that the data comes from a Normal (8, 4) distribution. Apply an appropriate statistical test to determine if Angus assumption is correct.
e. Comment on Angus assumption that the transit time data is normally distributed. Strictly considering what the data represents (transit times), why might we be surprised if the data is normally distributed? Again, based only on what the data represents, what other input distributions should be considered for this data? Finally, if the data was shown not to be normally distributed, why might a t-test be inappropriate for comparing the transit times for Firm A and Firm B? If a t-test is not appropriate, what statistical test (or tests) could or should we apply? Please note, there are no calculations required to complete this question.

Linkin Corporation is considering purchasing a new delivery
truck. The truck has many advantages over the company’s current
truck (not the least of which is that it runs). The new truck would
cost $55,400. Because of the increased capacity, reduced
maintenance costs, and increased fuel economy, the new truck is
expected to generate cost savings of $7,700. At the end of 8 years
the company will sell the truck for an estimated $27,500.
Traditionally the company has used a rule of thumb that a proposal
should not be accepted unless it has a payback period that is less
than 50% of the asset’s estimated useful life. Larry Newton, a new
manager, has suggested that the company should not rely solely on
the payback approach, but should also employ the net present value
method when evaluating new projects. The company’s cost of capital
is 8%.
Click here to view PV table.
(a)
Compute the cash payback period and net present value of the
proposed investment. (If the net present value is
negative, use either a negative sign preceding the number eg -45 or
parentheses eg (45). Round answer for present value to 0 decimal
places, e.g. 125. Round answer for Payback period to 1 decimal
place, e.g. 10.5. For calculation purposes, use 5 decimal places as
displayed in the factor table provided.)
| Cash payback period | enter the cash payback period in years rounded to 1 decimal place years | |||
|---|---|---|---|---|
| Net present value | $ | enter the net present value in dollars rounded to 0 decimal places |
(b)
Does the project meet the company’s cash payback
criteria?
| select between Yes or No YesNo |
Does it meet the net present value criteria for
acceptance?
| select between Yes or No YesNo |
