Answer:
Beta= 1.1065
Explanation:
Giving the following formula:
Proportions:
35 percent in Stock Q, 25 percent in Stock R, 25 percent in Stock S, and 15 percent in Stock T.
Betas:
0.83, 1.21, 1.22, and 1.39,
<u>To calculate the beta of the portfolio, we need to use the following formula:</u>
<u></u>
Beta= (proportion of investment A*beta A) + (proportion of investment B*beta B)
Beta= (0.35*0.83) + (0.25*1.21) + (0.25*1.22) + (1.15*1.39)
Beta= 1.1065
Answer:
b. abandon the production of airplane tires to fully specialize in the production of race car tires and then trade with Company Z for airplane tires.
Explanation:
Company X has a comparative advantage at producing race car tires
Company Z has a comparative advantage at producing airplane tires.
A country (company) has comparative advantage in production if it produces at a lower opportunity cost when compared to other countries (companies).
A company should specialise only in the production of the good for which it has a comparative advantage.
Company X should specialise in producing race car tires and stop producing airplane tires
Company Z should specialise in producing airplane tires and stop producing race car tires
Answer:
The optimistic approach examines the best possible outcome in a given situation and chooses the 'best of the best' while the pessimistic approach examines the worst possible outcome in a given situation and chooses the 'best of the worst'.
Explanation:
Decision making under assumed uncertainty is an approach that is taken when the outcomes of future events are not entirely known. The Hurwicz criterion provides a basis on which the pessimistic and optimistic outcomes can be balanced. This criterion allows the person who makes the decision to chose a coefficient of pessimism signified by alpha (α) and it is a decimal that is graded between 0 and 1. This number signifies the worst possible outcome whereas, the number (1-α) signifies the best outcome.
So, the optimistic approach examines the best possible outcome in a given situation and allows the decision-maker to choose the 'best of the best', while the pessimistic approach examines the worst possible outcome in a given situation and the decision-maker to choose the 'best of the worst'
The answer is true. I'm not sure but I hope you get it right.
