What is the correct interpretation for the correlation coefficient r=1r=1?

The scatter plot contains points which all lie on a horizontal line.
The scatter plot contains points which show no discernable relationship.
The scatter plot contains points that all lie on a line with negative slope.
The scatter plot contains points that all lie on a line with positive slope.

Solutions

Expert Solution
