Stock                  Amount                       Beta

A                         25,000                         0.2

C                         30,000                         1.8

D                         25,000                         1.6

Risk-free rate is 3% and the market risk premium is 8%.

If stock E with its beta of 0.6 and has an expected return of 8.2% should it be added to the portfolio?

Find the value of the probability of the standard normal variable Z corresponding to the shaded area under the standard normal curve. (Round your answer to four decimal places. You may need to use the appropriate table in the Appendix of Tables to answer this question.) P(0.2 < Z < 1.83) = ?

Consider an economy with the interest rate at r = 0.25 and no growth rate. The market where firms compete is very volatile and there is a high probability h = 0.2 that the industry collapse. Would the firms accept a collusive agreement to set monopoly price and share equally the market if I = {1, 2}?

Elasticity of demand curve 1 = - 0.5

Elasticity of demand curve 2 = - 2.5

Given an acid with a concentration of 0.4 M in a 1 liter solution, answer the following questions:

• What is the pH if pka = 4.76

• What is the pH after the addition of 0.2 mol NaOH (pka =4.76)?

• What is the ka of a solution with 0.65 M HA and 0.44 M A- (pH=6.0)

A five-year bond with a yield of 7% (continuously compounded) pays a 5.5% coupon at the end of each year.

1. What is the bond’s price?
2. What is the bond’s duration?
3. Use the duration to calculate the effect on the bond’s price of a 0.3% decrease in its yield.
4. Recalculate the bond’s price on the basis of a 6.7% per annum yield and verify that the result is in agreement with your answer to (c).

Suppose a batch of metal shafts produced in a manufacturing company have a standard deviation of 1.5 and a mean diameter of 205 inches.

If 79 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by less than 0.3 inches? Round your answer to four decimal places.

The nicotine content in a single cigarette of a particular brand has a distribution with mean 0.3 mg and standard deviation 0.1 mg. If 100 of these cigarettes are analyzed, what is the probability that the resulting sample mean nicotine content will be less than 0.29? (Round your answers to four decimal places.)
P(x < 0.29) =  

Less than 0.27?
P(x < 0.27) =  

The amount of icing on a Cuppie Cake large cupcake follows a Normal distribution, with a mean of 2 ounces and a standard deviation of 0.3 ounce. A random sample of 16 cupcakes is selected every day and measured. What is the probability the mean weight will exceed 2.1 ounces?
