3. In the US economy, nearly half of all workers employed by private firms work at the 0.3% of firms that have 500 or more employees.

a. What does this relationship mean for the power relationship between large firms and the labor force?

b. What do you think these large firms having such a market share of labor means for labor prices (wages)?

c. Can you propose a policy that would counteract this power imbalance?

The real risk-free rate, r*, is 1.6%. Inflation is expected to average 1.3% a year for the next 4 years, after which time inflation is expected to average 4.2% a year. Assume that there is no maturity risk premium. A 10-year corporate bond has a yield of 8.4%, which includes a liquidity premium of 0.3%.

What is its default risk premium? Do not round intermediate calculations. Round your answer to two decimal places.

QUESTION 19 For #18, what is the mean (expected) number of fraudulent claims in the sample?

a. 0.3 b. 0 c. 1.5 d. 0.9 e. 3

[Positive test] A patient is tested for a virus that is believed to be present in 5% of the population. If the test result is positive, compute the chance the patient actually has the virus… a. If the false-positive rate is 4% and the false-negative rate is 1% b. If the false-positive rate is 2% and the false-negative rate is 0.3% c. If the false-positive rate is 0.1% and the test never gives a false negative. d. If the test never gives a false-positive or a false-negative.

Q3. 40% of 500 employees of a company are females (other males). 30% of the employees are credit card

       holders, including 60 females. Use the contingency table for the problem situation to find the

       probability that an employee picked at random is:

       a. A female or is not credit card holder? (0.82) b. A male or a credit card holder? (0.72)   

       c. A female and a credit card holder? (0.12)

       d. A credit card holder if we know that the employee is a male? (0.3)

A statistician claims that the proportion of students who will vote for Mr. K to be the next president is 0.54 with the standard deviation of 0.3.

1. Identify the hypothesis test
2. If 1000 students are randomly selected and 455 of them will not vote for Mr. K, what is the P-value? What can you conclude based on 5% significant level?
3. Construct a 95% Confidence Interval
4. If Mr. K is ended up losing the election, does this make sense? Why or why not?
