Remove the data entry for the man who is 51 years old and has a systolic blood pressure of 198 millimeters of mercury from the data set and find the new correlation coefficient. Describe how this affects the correlation coeffcient r. Use technoogy 囲click the icon to view the data set. going from 0.921 to The new correlation coefficient r (Round to three decimal places a gets stronger, gets weaker, stays the same,
