Suppose the least-squares regression line for a set of data has slope 72.4. Now suppose we remove a point from the data, compute the least-squares regression line, and find that the new slope is 8.7. The point removed would be considered robust. influential. a response. a residual.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
