Answer:

E. None of these are resistant measures

Step-by-step explanation:

Outliers of a given distribution are values that are very far apart from other values of the distribution. When outliers are used in a calculation, they strongly affect the accuracy of the results.

Note that the slope, LSRL, correlation coefficient, and correlation of determination always give relationship between two connected variables in different ways. They always take the form of a line.

Therefore, the inclusion of outliers in their calculations always affect the result gotten. Hence, all of them are affected by outliers. That is, none of them is outlier resistant.
