American and Japanese workers can each produce 4 cars a year. An American worker can produce 10 tons of grain a year, whereas a Japanese worker can produce 5 tons of grain a year. To keep things simple, assume that each country has 100 million workers.
- For this situation, construct a table analogous to the table in Figure 1.
- Graph the production possibilities frontiers for the American and Japanese economies.
- For the United States, what is the opportunity cost of the car? Of grain? For Japan, what is the opportunity cost of a car? Of grain? Put this information in a table analogous to Table 1.
- Which country has an absolute advantage in producing cars? In producing grain?
- Which country has a comparative advantage in producing cars? In producing grain?
- Without trade, half of each country’s workers produce cars and half produce grain. What quantities of cars and grain does each country produce?
- Starting from a position without trade, give an example in which trade makes each country better off.
Let the mean concentration of particulate matter collected on filter paper is
45.6 ppm, with the standard deviation is 4.4 ppm. Find the probability that the
mean concentration of particulate matter in a sample of 87 filter papers will be
within 47 ppm of the guideline level.

report, the average rainfall for the year of 2019 was 300mm. Find the T-score of
this sample.
Body temperature is known to have normal distribution among healthy adults.
A researcher collected data from a random sample of 20 healthy adults. It was
found that the sample temperatures have a mean of 88.4oF and a sample
standard deviation of 0.3oF.

An analysis of the monthly allowances received by a sample of five engineers from a telco company has been conducted recently. The mean and median of the allowances is RM7000. A unimodal among the observations is RM12,000. Find the standard deviation if the allowances paid to each engineer were in full thousands.
A solid steel bar of diameter d1 = 25.0 mm is enclosed by a steel tube of outer diameter d3 = 37.5 mm and inner diameter d2 = 30.0 mm (see figure). Both bar and tube are held rigidly by a support at end A and joined securely to a rigid plate at end B. The composite bar, which has a length L = 550 mm, is twisted by a torque T = 400 N-m acting on the end plate.
(a) Determine the maximum shear stresses Ƭ1 and Ƭ2 in the bar and tube, respectively.
(b) Determine the angle of rotation ϕ (in degrees) of
the end plate, assuming that the shear modulus of
the steel is G = 80 GPa.
(c) Determine the torsional stiffness kT of the
composite bar.
