Answer:
The beta of the stock must be = 1.315 (approx).
Step-by-step explanation:
Considering the following formula, we get:
expected return = 16
Risk free rate = 6.4
Market risk premium = 7.3
expected return=risk-free rate+beta* market risk premium
hence
16 = 6.4 + beta * 7.3
hence beta=(16 - 6.4)/7.3 =1.315(approx).
