Question 31

Using the following hypothesis and data:

♣ H₀: a = b and H₁: a ≠ b

♣ The critical Z-statistic is 2.58

♣ The calculated Z-statistic is 4.1

An analyst should:

A) Reject the null hypothesis and conclude that a = b.

B) Reject the alternative hypothesis and conclude that a = b.

C) Reject the null hypothesis and conclude that a is significantly different than b.

D) Fail to reject the null hypothesis and conclude that we cannot say that a is significantly different than b.

Question 32

Shawn Choate is thinking about his graduate thesis. Still in the preliminary stage, he wants to choose a variable of study that has the most desirable statistical properties. The statistic he is presently considering has the following characteristics:

♣ The expected value of the sample mean is equal to the population mean.

♣ The variance of the sampling distribution is smaller than that for other estimators of the parameter.

♣ As the sample size increases, the standard error of the sample mean rises and the sampling distribution is centered more closely on the mean.

Select the best choice. Choate’s estimator is:

A) unbiased, efficient, and consistent.

B) unbiased and efficient.

C) efficient and consistent.

D) unbiased and consistent.

Question 33

An increase in the rate of the money supply growth most likely will lead to higher rates of:

A) inflation, expected inflation and nominal interest.

B) inflation and expected inflation, and a lower nominal interest rate.

C) nominal interest, and lower rates of inflation and expected inflation.

D) inflation and nominal interest, and a lower expected inflation rate.

Question 34

Economies and diseconomies of scale are most likely to determine the shape of the:

A) short-run average total cost curve.

B) short-run average fixed cost curve.

C) long-run average total cost curve.

D) long-run average fixed cost curve.

Question 35

The economy is in long-run disequilibrium with actual GDP less than potential GDP. One of the possible policy actions is to accelerate the rate of increase of the money supply to stimulate aggregate demand. Would this policy likely be recommended by Keynesian and Monetarist economists?

Keynesians Monetarists

A) Yes Yes

B) No Yes

C) No No

D) Yes No
