If the methods of this section are used with paired sample data, and the conclusion is that there is sufficient evidence to support the claim of a correlation between the two variables, can we use the methods of Section 10-2 to find the regression equation that can be used for predictions? Why or why not?

Regression equation:

The regression equation expresses a relationship between x (called the explanatory variable, or predictor variable, or independent variable) and ŷ (called the response variable or dependent variable).
