Answer: 5.36%
Explanation:
The formula for the effective annual yield (EAR) when the interest is compounded daily is given by:
(1 + r/365)^365 - 1
where r is the annual interest rate.
In this case, the annual interest rate is 5.2% or 0.052. Substituting this value into the formula, we get:
(1 + 0.052/365)^365 - 1 = 0.0536
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.0536 x 100 = 5.36%
Therefore, the effective annual yield of the account is 5.36%.
