Solution 1
To determine the covariance between two variables, we need to follow these steps:
- Calculate the mean of each variable.
- Subtract the mean from each value in the first variable to get the deviation of each value from the mean.
- Subtract the mean from each value in the second variable to get t Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
