The ages in years of 10 men and their systolic blood pressures in mm are shown inthe attached dat table with a sample correlation coefficient r of 0.906 remove the data entry for the man who is 49 and has a systolic blood pressure of 200 mm of mercury from the data set and find the new correlation coefficient. describe how this affects the correlation coefficient r the new correlation coefficient r? going from 0.906 to?
