An all-equity firm is considering the following projects: Project Beta IRR
W .67 9.5 %
X .74 10.6
Y 1.37 14.1
Z 1.48 17.1
The T-bill rate is 5.1 percent, and the expected return on the market is 12.1 percent.
a. Compared with the firm's 12.1 percent cost of capital, Project W has a lower expected return, Project X has a lower expected return, Project Y has a higher expected return, and Project Z has a higher expected return.
b. Project W should be rejected , Project X should be accepted , Project Y should be rejected , and Project Z should be accepted .

Projects W and X have lower expected returns

Projects Y and Z have higher expected returns

Explanation:

Given

Solving (a): Compare the expected return of each project to 12.1%

Expected Return of each project is calculated as:

For Project W:

Lower Expected return

For Project X:

Lower Expected return

For Project Y:

Higher Expected return

For Project Z:

Higher Expected return

There is no question in (b)

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
