In the year 2000, the Chinese economy’s growth was not as fast as the government expected. The Chinese government prolonged the Labour Day vacation (in May) to 7 days so that people could spend more.

a. Explain this decision, using the model of aggregate demand and aggregate supply.

b. Why did the Chinese government not wait until the economy adjusted back to its expected long-run position of high economic growth?

1) Computer equipment was acquired at the beginning of the year at a cost of $53,900. It had an estimated residual value of $4,300 and an estimated useful life of 5 years.

a. Determine the depreciable cost.

b. Determine the straight-line rate.

c. Determine the annual straight-line depreciation.

2) A machine costing $45,000 with a 5-year life and $2,700 residual value was purchased January 2. Compute depreciation for each of the five years, using the double-declining-balance method.

You will be paying $11,000 a year in tuition expenses at the end of the next two years. Bonds currently yield 10%.

a. What is the present value and duration of your obligation? (Do not round intermediate calculations. Round "Present value" to 2 decimal places and "Duration" to 4 decimal places.)

b. What is the duration of a zero-coupon bond that would immunize your obligation and its future redemption value? (Do not round intermediate calculations. Round "Duration" to 4 decimal places and "Future redemption value" to 2 decimal places.)

c. Suppose you buy a zero-coupon bond with value and duration equal to your obligation. Now suppose that rates immediately increase to 11%. What happens to your net position, that is, to the difference between the value of the bond and that of your tuition obligation? (Enter your answer as a positive value. Do not round intermediate calculations. Round your answer to 2 decimal places.)

d. What if rates fall to 9%? (Enter your answer as a positive value. Do not round intermediate calculations. Round your answer to 2 decimal places.)

If a merchant deposits $ 1500 annually at the end of each fiscal year into a retirement account that pays interest at the rate of 8% per year compounded annually, how much money will he have in his account at the end of 25 years?

Payments of $6,000.00 are made into a fund at the beginning of each year for ten years. The fund is invested at an annual effective rate of i. The interest generated is reinvested at 10%. The total accumulated value at the end of the ten years is $98,180.00. Find I round to 3 decimal places

The table below shows the number of deaths in the U.S. in a year due to a variety of causes. For these questions, assume these values are not changing from year to year, and that the population of the United States is 312 million people.

g) People sometimes claim skydiving is less dangerous than driving or riding in a car. Does the data support this claim? Explain.

In any given year, an insurance company believes the following:

-0.6 of drivers are safe.

-0.25 of safe drivers wear seatbelts

-0.10 of unsafe drivers wear seatbelts

-0.10 of safe drivers experience an accident in a year

-0.20 of unsafe drivers experience an accident in a year

-Given a driver experiences an accident, the driver has probability 0.01 they will be taken to the hospital if they were wearing a seatbelt

-Given a driver experiences an accident, the driver has probability 0.2 they will be taken to the hospital if they were not wearing a seatbelt

What is the probability a driver will be taken the hospital this year (as a result of an accident)? Given that a driver wears a seatbelt, what is the probability he/she will be taken to the hospital this year?

a) A magazine collects data each year on the price of a hamburger in a certain fast food restaurant in various countries around the world. The price of this hamburger for a sample of restaurants in Europe in January resulted in the following hamburger prices (after conversion to U.S. dollars).

The mean price of this hamburger in the U.S. in January was $4.61. For purposes of this exercise, assume it is reasonable to regard the sample as representative of these European restaurants. Does the sample provide convincing evidence that the mean January price of this hamburger in Europe is greater than the reported U.S. price? Test the relevant hypotheses using  α = 0.05.

(Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

t= __

p- value = ___

b) The risk of developing iron deficiency is especially high during pregnancy. Detecting such a deficiency is complicated by the fact that some methods for determining iron status can be affected by the state of pregnancy itself. Consider the following data on transferrin receptor concentration for a sample of women with laboratory evidence of overt iron-deficiency anemia.

(a) Compute the values of the sample mean and median. (Round your answers to two decimal places.)

Which of the mean and median do you regard as more representative of the sample, and why?

choice a) The mean is always more representative of a sample.

choice b)The mean because it is not influenced by the three extreme values at the upper end of the distribution.  

choice c) The median because it is not influenced by the three extreme values at the upper end of the distribution.

choice d) The median is always more representative of a sample.
