Question 2: Problem solving
Kenneth Brown is the principal owner of Brown Oil, Inc. After quitting his university teaching job, Ken has been able to increase his annual salary by a factor of over 100. At the present time, Ken is forced to consider purchasing some more equipment for Brown Oil because of competition. His alternatives are shown in the following table:

For example, if Ken purchases a Sub 100 and if there is a favorable market, he will realize a profit of $300,000. On the other hand, if the market is unfavorable, Ken will suffer a loss of $200,000. But Ken has always been a very pessimistic decision maker.
If information about the probability of each outcome becomes available to Ken then:
Questions:
4. Find the best decision using the adequate technique.
5. How much Ken should pay to know the perfect information about the market condition?
6. Is it reasonable for Ken to purchase the perfect information about the market outcomes for $20,000? Explain why. (1 Mark)

The budgeted and actual data for direct materials and labor are as
follows:
| Budgeted | Actual | |
| DM price | $3 per pound | $2.75 per pound |
| DM quantity per unit | 3 pounds per unit | 4 pounds per unit |
| DL price | $10 per hour | $13 per hour |
| DL quantity per unit | 0.2 hours per unit | 0.3 hours per unit |
Actual sales volume is 100 units. Budgeted sales volume is 80 units.
Compute the input price and input efficiency variances
for DM and DL.
As a preliminary step, compute actual input quantity (total pounds
or hours we actually used) and flexible budget input quantity
(total pounds or hours we should have used for actual
output):
actual input quantity for DM =
___________pounds
flexible budget input quantity for DM = ________
pounds
actual input quantity for DL = __________
hours
flexible budget input quantity for DL =
__________ hours
Next, compute the variances. Enter favorable variances as a
positive number and unfavorable variances as a negative number. Do
NOT enter F or U.
input price variance for DM = $
___________
input efficiency variance for DM = $
____________
input price variance for DL = $ __________
input efficiency variance for DL = $

Research Scenario: Does distraction and/or amount of details affect the ability of people to make good decisions? In this fictitious scenario, researchers used a mixed design. Thirty participants were split into two groups – No Distraction or Distraction (n=15 per group). All participants were given TWO scenarios based on amount of details (4 or 12), and were asked to make an objective decision at the end of each scenario. Objective decision was the dependent variable and was quantified numerically using an interval scale of measurement.
Assume the data is parametric. Select and conduct the most appropriate statistical test to determine whether distraction and/or amount of details affect people’s ability to make good decisions.

Consider the following numerical example using the Solow growth model.
Suppose that F(K, N) = K^(4/13)N^(9/13), Y = zF(K.N).
Furthermore, assume that the capital depreciation rate is d = 0.04, the savings rate is s = 0.3, the population growth rate is n = 0.035, and the productivity is z = 1.75. Suppose K0 = 200 and N0 = 100.
1. Compute the values k1, y1, and c1 of the per-worker capital, output and consumption in period one. Find the steady state per-capita capital stock (k*), output per capita (y*), and consumption per capita (c*).
2. Assume the economy is in the steady state of Question 2, compute the percentage change in z that is needed to increase the long run per capita capital by 5%.
3. Assume the economy is in the steady state of Question 2 and suddenly, z decreases by 10%, calculate the percentage change in s that is needed to keep the long run per capita output unchanged.
4. Assume the economy is in the steady state of Question 2 and n goes down by 5% while z increases by 5% and s increases by 5%. Using the Taylor approximation, evaluate the contribution of each variable to the total change in the steady state consumption c*.

Abstract ‘In the present study, we report an efficient invitro propagation system. Shoot apices of six weeks old in vitro grown G. scabra plants were used as explants for the in vitro propagation. Induction of multiple shoots (9.1/explant) was achieved on the culture of shoot apices on half strength Murashige and Skoog’s basal medium (MSBM) containing 2.0 mg/L−1 6-benzylaminopurine (BA), 3% sucrose and 0.9% Difco agar. In vitro shoots induced profuse rooting on half strength of MSBM supplemented with 0.1 mg/L−1 1-naphthaleneacetic acid (NAA), 3% sucrose and 0.3% gelrite. A two-stage ventilation closure procedure during the in vitro culture, and transparent sachet technique enhanced the survival rate of G. scabra plantlets to 96% in the greenhouse. Tissue culture plants flowered after 5 months of transfer to pots.A simple and an efficient in vitro propagation protocol of Gentiana scabra Bunge by optimizing the medium composition and ventilation closure treatments has been developed. The protocol can be very useful in germplasm conservation and commercial cultivation of G. scabra plants’’.
