The management of a company is considering replacing a number of old looms in the mill’s weave room. The looms to be replaced are two 220-cm President looms, sixteen 135-cm President looms, and twenty-two 185-cm Draper X-P2 looms. The company may either replace the old looms with new ones of the same kind or buy 21 new shutterless Pignone looms. The first alternative requires the purchase of 40 new President and Draper looms and the scrapping of the old looms. The second alternative involves scrapping the 40 old looms, relocating 12 Picanol looms, and constructing a concrete floor, plus purchasing the 21 Pignone looms and various related equipment. Following are the revenue and expense predictions:
| Description | Alternative 1 | Alternative 2 |
| Machinery/related equipment | $2,150,000 | $900,000 |
| Annual revenues due to the new looms | $2,000,000 | $1,500,000 |
| Annual labour cost | $250,000 | $300,000 |
| Annual O&M cost | $1,000,000 | $700,000 |
| CCA Rate | 30% | 30% |
| Project life | 8 years | 8 years |
| Salvage value | $100,000 | $40,000 |
The corporate executives feel that various investment
opportunities available for the mill will guarantee a rate of
return on investment of at least (MARR) 10%. The mill’s marginal
tax rate is 40%. Due to uncertainty, the following variabilities in
estimates should be considered: revenues ± 30%, labour cost ± 40%,
and annual O&M cost ± 20%. Assume that each of these variables
can independently deviate from its base value.
a] Assuming that uncertain variables change once at a time, use NPW
to conduct sensitivity analysis. Ideally, you should plot the
relationship between percentage change in a variable and NPW.
b] Now consider that each variable can take only three possible
outcome within the range of possible outcome: lowest value, base
value, and highest value. Each outcome can happen with a
probability: 0.15, 0.7, and 0.15, respectively. Considering the
distributions of the three uncertain variables, predict the
probability distribution of NPW for each alternative. Each NPW will
have 27 possible outcome (3x3x3) and you are required to do that
for each alternative.
c] If Alternative 1 is chosen over Alternative 2, what is the
probability that this decision is correct?
Hints:
-do not forget to calculate income taxes and disposal tax
effects
-You can you spreadsheet applications if you communicate your
solution in a way which enables the teaching assistant to
independently replicate your final answer. You can show sample
calculations as a way to communicate with the teaching
assistant.
-Please assume that the given MARR is market interest rate and all
dollars are current.
Note: If not mentioned, [1] the half-year rule applies and [2] all rates are annual.
(could i get an example calculations and explanations as to why things are like that?)

An industrial engineer conjectures that a major difference between successful and unsuc- cessful companies is the percentage of their manufactured products returned because of defectives. In a study to evaluate this conjecture, the engineer surveyed the quality control departments of 35 successful companies (identified by the annual profit statement) and 35 unsuccessful companies. The companies in the study all produced products of a similar nature and cost. The successful companies selected had a mean percentage of total output returned by customers in the previous year of 5.51 with a standard deviation of 2.74, and the unsuccessful companies had a mean of 7.13 with standard deviation of 2.32. Is there suffi- cient evidence that successful companies have a lower percentage of their products returned by customers? Use α = 0.05.
1. State the null and alternative hypotheses for this problem.
2. Find the observed value of the test statistic.
3. Suppose you reject the null hypothesis. What conclusion can you make in terms of the problem?

) A major airline is concerned that the waiting time for
customers at its ticket counter may be exceeding its target average
of 190 seconds. To test this, the company has selected a random
sample of 100 customers and times them from when the customer first
arrives at the checkout line until he or she is at the counter
being served by the ticket agent. The mean time for this sample was
202 seconds with a standard deviation of 28 seconds. Given this
information and the desire to conduct the test using an alpha level
of 0.02, which of the following statements is true?
A) The chance of a Type II error is 1 - 0.02 = 0.98.
B) The test to be conducted will be structured as a two-tailed
test.
C) The test statistic will be approximately t = 4.286, so the null
hypothesis should be rejected.
D) The sample data indicate that the difference between the sample
mean and the hypothesized population mean should be attributed only
to sampling error.

Glenn Dental Clinic provides general dental care to residents of Philadelphia on a walk-In basis. The clinic has started receiving complaints from patients that the waiting time is too long and has asked you to Investigate whether this problem can be solved.
Upon arrival, customers receive a form from the receptionist and fill out relevant information such as personal health records and Insurance provider. The form is then handed back to the receptionist who enters the Information Into the computer system for the dentıst to see. A dental assistant then takes an X-ray from the patient. A dentist then performs the checkup and discusses any Issues with the patient.
Based on conversations with staff members at the clınic, you have obtained the following information on the process:
- It takes about 5 minutes for a customer to fill out the paperwork.
- Entry of Information on the paperwork Into the system and verification with past records takes another 5 minutes for a receptions There are two receptionists.
- It takes 15 minutes, on average, for the dental assistant to take an X-ray. There are three dental assistants on shift at any moment.
- There are 10 dentists working at the clinic. Each checkup takes 30 minutes, on average.
The following table summarizes the process data collected above.
| Resource | Process | Staffing (Number of Workers) | Processing Time (Minutes per Patient) |
|---|---|---|---|
| A. Self-serve | Paperwork | - | 5 |
| B. Receptionists | Data Entry | 2 | 5 |
| C. Dental assistant | X-ray | 3 | 15 |
| D. Dentist | Checkup | 10 | 30 |
This clinic has essentially unlimited demand. The dentists get paid $100 per hour while the receptionists and dental assistants get paid $30 per hour.
a. What is the labor content?
b. What is the cost of direct labor?
c. What is the labor utilization of the Receptionists?
d. What is the labor utilization of the Dental assistants?
e. What is the average labor utilization of the clinic?
f. If they hired three additional workers and assigned each of them to one of the four resources, what would their capacity be (patients per hour)?
g. What would be the capacity of this process (customers per hour) if they were able to integrate work between the dental assistants and the dentists? To be specific, they would have 13 workers doing the X-ray and checkup tasks with a total processing time of 45 minutes.
