A study indicates the correlation coefficient between salt intake and blood pressure is 0.8. If we plot the data points using salt intake as X axis, and blood pressure as Y axis. What will show on the plot?
1. The data points are clustered close to a line that slopes down to the right
2. The data points are clustered close to a line that slopes up to the right
3. The data points are scattered around a line that slopes down to the right
4. The data points are scattered around a line that slopes up to the right
Homework Answers
correlation coefficient between salt intake and blood pressure is 0.8 which is strongly and positively correlated.
If we plot the data points using salt intake as X axis, and blood pressure as Y axis.
Then it shows that the data points are clustered close to a line that slopes down to the right.
