Consider the following statements:

1. If the correlation coefficient r_xy = 0, then the two lines of regression are parallel to each other.

2. If the correlation coefficient r_xy = + 1, then the two lines of regression are perpendicular to each other.

Which of the above statements is/are correct

1 only

2 only

Both 1 and 2

Neither 1 nor 2

If r = 0, lines of regression are perpendicular and when r = 1, lines of regression are so, both statement are wrong.
