True or False? In Exercises 25-30, determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false.
A linear regression model with a positive correlation coefficient will have a slope that is greater than 0.
Whether the statement “A linear regression model with a positive correlation co-efficient will have a slope greater than 0” is true or false.
The least-squares linear regression model can be represented as:
Here, a and b are the slope and intercept for the regression line respectively.
In a linear regression model, the sign of the slope coefficient depends on the sign of the regression coefficient
