Explanation:
To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,
r = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability of state occurrence
- rA, rB, ... represents return A, return B and so on under each state
r = 0.2 * 0.16 + 0.4 * 0.12 + 0.2 * 0.05 + 0.2 * -0.05
r = 0.08 or 8%
The formula to calculate the standard deviation of a stock/investment is as follows,
SD = √pA * (rA - r)² + pB * (rB - r)² + ... + pN * (rN - r)²
SD = √0.2 * (0.16 - 0.08)² + 0.4 * (0.12 - 0.08)² + 0.2 * (0.05 - 0.08)² + 0.2 * (-0.05 - 0.08)²
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent

a. The discount rate is the
- interest rate at which banks can borrow reserves from the Federal Reserve.
The discount rate is the interest rate that the FED charges commercial banks, credit unions, or other financial institutions for lending them money.
b. If the Fed were to decrease the discount rate, banks will borrow
- more reserves, causing an increase in lending and the money supply.
Lowering the discount rate is considered part of an expansionary monetary policy since banks will borrow more money and lend more money to the public, increasing the money supply.
