Suppose that the index model for stocks A and B is estimated from excess returns with the following results: A: 34X1.15RMA RB-1.5X1.30M+08 15XR-qarA0.26R-q0.16 What is the covariance between each stock and the market index? Note: Calculate using numbers in decimal form, not percentages. For example, use 20 for calculation if standard deviation is provided as 20%. Do not round your intermediate calculations. Round your answers to the nearest whole number. To calculate the covariance between each stock and the market index, we need to extract the relevant information from the given text. However, the provided text contains several errors and is not clear. Therefore, it is not possible to accurately determine the covariance without further clarification and correction of the text.
