Answer:
7.7%
Step-by-step explanation:
Risk premium is the return an investor would want for holding a risky bond. It is the excess return earned over holding a risk free bond
Risk premium = return on risky asset - return on U.S. Treasury bills
The U.S. Treasury bills is considered to be risk free because the US government cannot default
On the other hands, stocks are risky because companies can default on payment of dividends due to various reasons e.g. insolvency
11.7 - 4 = 7.7%
