← The correlation between the heights of some children in centimetres and their masses in kilograms is found to be 0.85. Every height is now written in metres and every mass in grams. What is the correlation between the new numbers?
For some data the correlation coefficient is 0.5, the standard deviation of x is 4 and the standard deviation of y is 12. What is the slope of the regression line of y on x? →
