Computation of the correlation (ρ) of Walden's stock with the market:-

Correlation Coefficient = Covariance with market / ( Standard Deviation of Stock * Standard Deviation of Market)

= 0.0068 / (16.4% * 12.7%)

= 0.0068 / 0.0208

= 0.3265

 

Computation of the beta (β) of Walden Books' stock:-

Variance of market = (Standard deviation)^2

= (12.7%)^2

= 0.01613

Beta of stock = Covariance of stock and market return / Variance of market

= 0.0068 / 0.01613

= 0.42
