Question
The ages of 10 men and their systolic blood pressures are shown in the attached data table with a sample correlation coefficient r of 0.898. Remove the data entry for the man who is 50 years old and has a systolic blood pressure of 201 millimeters of mercury from the data set and find the new correlation coefficient. Describe how this affects the correlation coefficient r. Use technology.
