In a market with two sectors, one which is covered by minimum wage legislation and one which is not, the migration of unemployed workers from the covered sector to the uncovered sector will

A) All of these are correct

B) Increase the level of employment in the uncovered sector

C) Reduce wages in the uncovered sector

D) Reduce the negative employment effects of the minimum wage in the uncovered sector

Employment may increase after an increase in the minimum wage when

A) more people want to work at the new, higher wage.

B) the minimum wage is below the equilibrium level of wages.

C) discouraged workers drop out of the labor market.

D) independently, labor demand increases significantly at the same time.

Consider two populations of coins, one of pennies and one of quarters. A random sample of 25 pennies was selected, and the mean age of the sample was 32 years. A random sample of 35 quarters was taken, and the mean age of the sample was 19 years.

For the sampling distribution of the difference in sample means, have the conditions for normality been met?

• Yes, the conditions for normality have been met because the distributions of age for the two populations are approximately normal.

  A

• Yes, the conditions for normality have been met because the sample sizes taken from both populations are large enough.

  B

• No, the conditions for normality have not been met because neither sample size is large enough and no information is given about the distributions of the populations.

  C

• No, the conditions for normality have not been met because the sample size for the pennies is not large enough and no information is given about the distributions of the populations.

  D

• No, the conditions for normality have not been met because the sample size for the quarters is not large enough and no information is given about the distributions of the populations.

• E

For a weekly town council meeting in a certain town, the distribution of the duration of the meeting is approximately normal with mean 53 minutes and standard deviation 2.5 minutes. For a weekly arts council meeting in the same town, the distribution of the duration of the meeting is approximately normal with mean 56 minutes and standard deviation 5.1 minutes. Let x¯1x¯1 represent the average duration, in minutes, of 10 randomly selected town council meetings, and let x¯2x¯2 represent the average duration, in minutes, of 10 randomly selected arts council meetings.

Which of the following is the best reason why the sampling distribution of x¯1−x¯2x¯1−x¯2 can be modeled by a normal distribution?

• The sample sizes are equal.

  A

• Both sample sizes are large enough to satisfy the normality condition.

  B

• The population distributions are approximately normal.

  C

• The population standard deviations are assumed equal.

  D

• The sample sizes are less than 10% of the corresponding population sizes.

• E

Two spheres have the same diameter and mass, but one is solid and the other one is hollow. Assuming homogeneous densities and putting the origin at the center, calculate the inertia tensor of each sphere.

Elasticity a. Use two diagrams (one for Alberta, one for the world) to explain why the following might be true: A drought around the world raises the total revenue that farmers received from the sale of grain, but a drought only in Albert reduces the total revenue that Alberta farmers receive.

b. You have the following information about good X and good Y: • Income elasticity of demand for good X: -3 • Cross-price elasticity of demand for good X with respect to the price of good Y: 2 Would an increase in income and a decrease in the price of good Y unambiguously decrease the demand for good X? Why or why not?

c. A price change causes the quantity demanded of a good to decrease by 30 percent, while the total revenue of that good increases by 15 percent. Is the demand curve elastic or inelastic? Explain

A  firm is considering the purchase of one of two machines to replace an existing one. MachineA will cost GBP £18,000 and has a four-year life. Annual net cash flows are expected to be GBP£7,200, beginning one year after the machine is purchased. Machine B will cost GBP £26,000and has a six-year life. Annual net cash flows are expected to be GBP £7,500, beginning oneyear after the machine is purchased. Assume the firm's cost of capital is a constant 15%forever, and there is no value to flexibilityas these machines will continue to be manufactured

Which of the following statements is incorrect?

a)The NPV of Machine A is greater than the NPV of Machine B

b)Machine B has a lower equivalent annual cash flow (or equivalent rental value) thanMachine A

c)Machine B has an equivalent annual cash flow (or equivalent rental value) greater than GBP£700

d)Machine A has an equivalent annual cash flow (or equivalent rental value) greater than GBP£700

e)Machine B has an equivalent annual cash flow (or equivalentrental value) that is less thanGBP £2000 per year higher than Machine A (to the nearest pound).

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 22 m/s. The masses of the two objects are 3.2 and 8.0 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.

(a) v_f =  

(b) v_f =  

If two continuous measures are positively correlated with one another, does that mean that one of them caused the other? Why or why not?If two continuous measures are positively correlated with one another, does that mean that one of them caused the other? Why or why not? (THIS IS FOR MY MKT RESEARCH CLASS)
