variables X and Y have a correlation coefficient r035 if we

variables X and Y have a correlation coefficient r=0.35. if we decrease each Y value by 0.20, double each X value, and then interchange them (put X on the vertical axis and Y on the horizontal axis) the new correlation coefficient will be: 1) r= 0.70. 2) r= 0.50. 3) r= 0.90. 4) r = 0.35 5) can not be detrmined

Solution

The correlation will not change (still will remain r=0.35) because correlation does not depend on scale, position and which variable is dependent and independent.
