Samantha Xiao is trying to get some insight into the relationship between the return on stock LMD (R_LMD,t) and the return on the S&P 500 index (R_S&P,t). Using historical data she estimates the following:

• Annual mean return for LMD: 11%
• Annual mean return for S&P 500 index: 7%
• Annual volatility for S&P 500 index: 18%
• Covariance between the returns of LMD and S&P 500 index: 6%

Assuming she uses the same data to estimate the regression model given by:

$$R_{LMD,t} = \alpha + \beta R_{S\&P,t} + \varepsilon_t$$

Using the ordinary least squares technique, which of the following models will she obtain?_
