Answer:
The standard deviation of the returns on the stock is 15.56%(Approx).
Explanation:
Expected Return=Respective return*Respective probability
=(20.4*0.67)+(-12.7*0.33)=9.477%
probability Return probability*(Return-Expected Return)^2
0.67 20.4 0.67*(20.4-9.477)^2=79.93899243
0.33 -12.7 0.33*(-12.7-9.477)^2=162.3003786
Total=242.239371%
Standard deviation=[Total probability*(Return-Expected Return)^2/Total probability]^(1/2)
=15.56%(Approx).
The spending that would occur during the third round of spending if the marginal propensity to consume (MPC) was 0.6 will be $420 billion.
- Increase in expenditure = $700 billion.
- Marginal propensity to consume = 0.6
The amount of spending based on the information given will be:
= 0.6 × $700 billion
= $420 billion.
Therefore, the correct option is $420 billion.
