Final answer:
The risk premium for Idaho Bakery stock is calculated using the CAPM formula, which results in a risk premium of 10.25%.
Step-by-step explanation:
The risk premium for Idaho Bakery stock, which has a beta of 1.57, can be calculated using the Capital Asset Pricing Model (CAPM). According to CAPM, the risk premium is the expected return on the market minus the risk-free rate, adjusted for the stock's volatility as measured by its beta.

Risk Premium = (Beta × (Expected Market Return - Risk-Free Rate))
In this case:
Risk Premium = (1.57 × (11.15% - 4.62%)) = 1.57 × 6.53% = 10.25%
Therefore, the risk premium for Idaho Bakery stock is 10.25%.
