Transcript text: Determine the linear correlation coefficient between compensation and stock return.
\[
\mathrm{r}=\square
\]
(Round to three decimal places as needed.)
Solution
Solution Steps
Step 1: Calculate Covariance
The covariance between compensation \( X \) and stock return \( Y \) is calculated as follows:
\[
\text{Cov}(X,Y) = 2500.0
\]
Step 2: Calculate Standard Deviations
Next, we calculate the standard deviations of both variables:
\[
\sigma_X = 158.114
\]
\[
\sigma_Y = 15.811
\]
Step 3: Calculate Correlation Coefficient
The correlation coefficient \( r \) is computed using the formula:
\[
r = \frac{\text{Cov}(X,Y)}{\sigma_X \sigma_Y}
\]
Substituting the values we have:
\[
r = \frac{2500.0}{158.114 \times 15.811} = 1.0
\]
