Answer:

E) Select at random 50 apartments from all the apartments in the 10 buildings.

Explanation:

Unbiased sampling is when each element has an equal chance of getting picked out of a sample population.

In this case, a random selection of 50 apartments from all the 10 buildings gives each apartment an equal probability to get selected while all other options introduce some sort of a bias. There fore the option that gives unbiased opportunity of selection is option E.

Hope that helps.

Kisachek [45]
<span>The kidnappers have taken and holding eight people hostage at a farmhouse just outside town. If the Swat team assaults the farmhouse, hostages will be killed. If they give into the kidnappers' demands for ransom, hostages will be safe but the tactic will encourage more kidnappings of innocent people.The argument is an example of compromise. </span>

<span>Compromise is a  negotiation process in which both parties (Swat team and kidnappers)  give up something in order to get something else which they want more. It occurs  in win-lose situations – like in the example that there are hostages taken in. Each of the parties makes concessions in order to reach an agreement that is agreeable to both.</span>

An all-equity firm is considering the following projects:
FromTheMoon [43]

Answer:

Projects Y and Z

b. Projects W and Z

c. Projects W and Y

Explanation:

CAPM equation : Expected return = Risk free rate + Beta x (Expected market return - Risk free rate)

W = 4% + [0.85 x (11% - 4%)] = 9.95%

X = 4% + (0.92 x 7%) = 10.44%

Y = 4% + (1.09 x 7%) = 11.63%

Z = 4% + (1.35 x 7%) = 13.45%

Projects Y and Z have an expected return greater than 11%

b. Projects W and Z should be accepted because its expected return is higher than the IRR

c. Project W would be incorrectly rejected because the expected rate of return is less than the overall cost of capital (i.e. 9.95 is less than 11). But its expected rate of return is greater than the IRR

Y would be incorrectly accepted because its expected rate of return is greater  than the overall cost of capital but its expected rate of return is less than the IRR
