A state's environmental agency worries that a larger percentage of cars may be violating clean air standards. In the past, the percentage of cars that violate clean air standards has been 10%. The agency hopes to check a sample of vehicles in order to estimate that percentage with a margin of error of 1% and with 99% confidence.

How many cars should be sampled? Show your work! Formula(s), substitutions, answer! Round your z or t value to 3 decimal places.

In the following Table you are given information on Real GDP and Nominal GDP.

Compute the percentage change in Nominal GDP from 1970 to 1980 (15 points) and the percentage change in Real GDP (15 points) from 1970 to 1980.

Where do you attribute the difference between the two percentage changes?

Environmentalists concerned about the impact of high-frequency radio transmissions on birds found that there was no evidence of a higher mortality rate among hatchlings in nests near cell towers. They based this conclusion on a test using alpha=0.05. Would they have made the same decision at alpha=0.10? How about alpha=0.01? Explain. (Hint: It would help if you write the null and alternative hypotheses).

1.Describe the two different ways in which an ADI may be exposed to interest rate risk.  What would it do – in respect of the two different aspects of interest rate risk – if it thought interest rates were going to increase in the near future and wanted to take advantage of this prediction?  Explain how these actions will be of benefit if interest rates do increase as predicted?

2.Describe how a bank could use derivatives to hedge an exposure to decreasing interest rates.
