The expected value for the number of cars with defects can be obtained by multiplying the probability of success (i.e. the percentage of products with defects - 40%) by the number of cases (i.e. the number of cars purchased – 5).

 

40 / 100 X 5 = 2

 

Therefore, the expected value for the number of cars with defects will be the percentage of products with defects is 2

yKpoI14uk [10]

The available options are the following:

-Board members serve on multiple boards

-People with knowledge of the firm's history are replaced with those who may not know as much information

-Less frequent board meetings

-Better decisions about important issues

Answer:

-People with knowledge of the firm's history are replaced with those who may not know as much information

Explanation:

Considering the available options, the option that appears negative and related to the point being discussed is

"People with knowledge of the firm's history are replaced with those who may not know as much information."

It is straightforward, as changing the board of directors will at some point lead to a time where the new member in the board of directors will just be a competent worker but has no history with the company.

Suppose you are currently invested 100% in U.S. stocks and you CANNOT short: a.Find the portfolio that maximizes expected return
Volgvan

Answer:

Part a: The portfolio which maximizes the expected return is in the attached file.

Part b:The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.

Explanation:

As the question is incomplete and the data is not available, thus the complete question is found as attached with the solution.

The Sharpe rate is given as

S_a=\frac{E_a-E_r}{\sigma}

Where

  1. E_a is the estimated rate of return for a value
  2. E_r is the risk free rate of return
  3. σ is the standard deviation of the investment.

The portfolio variance is given as

\sigma^2_{portfolio}=\sum_{i}^{n}{\sigma_i^2w_i^2}+\sum_{i}^{n(n-1)/2}{cv_i}

Where

  1. σ is the standard deviation of the investment.
  2. w is the weighted value of the investment
  3. cv is the covariance term

Portfolio standard deviation is given as

\sigma_{portfolio}=\sqrt{\sigma^2_{portfolio}}

Expected rate is given as

E_{rate of return}=\sum_{i=1}^{n}{E_a_i\times w_i}

Now the Sharp value is calculated as above.

Now the values as given in the excel sheet are added in the attached excel sheet,  following formulas are used to calculate various values

Sharpe ratio is calculated using =(B6-J3)/C6

Portfolio variance is calculated using (=B13^2*C6^2+B14^2*C7^2+B15^2*C8^2+B16^2*C9^2+2*B13*B14*C6*C7*D7+2*B13*B15*C6*C8*D8+2*B13*B16*C6*C9*D9+2*B14*B15*C7*C8*E8+2*B14*B16*C7*C9*E9+2*B15*B16*C8*C9*F9)

Portfolio standard deviation is SQRT(Variance)

Expected return is calculated using =B13*B6+B14*B7+B15*B8+B16*B9

Sharpe is calculated using =(B23-$J$3)/B22

Part a:

The portfolio which maximizes the expected return is in the attached file.

Part b:

The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.
