1. Explain what a correlation coefficient of -1 indicates about the relationship between two variables.
2. Describe a scenario where the correlation coefficient, r, would be close to zero.
3. If a scatter plot shows data points clustered closely around a line with a positive slope, what would you expect the value of the correlation coefficient, r, to be? Explain your reasoning.
