Explanation / Answer

Answer:

8) The correlation coefficient, r, is always a number between -1 and 1.

9) if the value of r is close to -1 and 1 then the association of the variables is very strong and if it is close to 0 the association is very weak.

10) the coefficient of determination, r -squared, is between 0% and 100%.

11) if the value of the r-squared is 100% then the relation of the variable is perfectly strong and if the value is 0% means there is no relationship.

12) Residuals

13) Weak

14) Normality
