What is the correlation coefficient with the outlier? \[ r_w = \]2. What is the correlation coefficient without the outlier? \[ r_{wo} = \]3. Would inclusion of the outlier change the evidence for or against a significant linear correlation? - ☐ Yes. Including the outlier changes the evidence regarding a linear correlation. - ☐ No. Including the outlier does not change the evidence regarding a linear correlation.This table presents two variables, x and y, which appear to be related, but contain an outlier in the data. The questions guide an analysis of how the outlier affects the correlation coefficient, indicating the strength and direction of a linear relationship between x and y.

Use EXCEL to obtain the value correlation coefficient r with the outlier. EXCEL procedure: Go…
