question 2

Multiple Choice

Which of the following formula is used to compute covariance between two variables X and Y?

• A) \( \operatorname{cov}(\mathrm{X}, \mathrm{Y})=\frac{\sum_{i=1}^{N}\left(x_{i}-\mu_{x}\right)\left(y_{i}-\mu_{y}\right)}{N} \)
• B) \( \operatorname{cov}(\mathrm{X}, \mathrm{Y})=\frac{\sum_{i=1}^{N}\left(x_{i}-\mu_{x}\right)^{2}}{N} \)
• C)\( \operatorname{cov}(\mathrm{X}, \mathrm{Y})=\sum_{i=1}^{N} \frac{\left(x_{i}-\mu_{x}\right)^{2}}{y_{i}-\mu_{y}} \)
• D) \( \operatorname{cov}(\mathrm{X}, \mathrm{Y})=\sqrt{\frac{\sum_{i=1}^{N}\left(x_{i}-\mu_{x}\right)^{2}}{N^{2}}} \)
