List of top Statistics Questions on Correlation and Regression asked in CUET (PG)

If the two regression lines are given by \(8X-10Y+66=0\) and \(40X-18Y=264\), then the correlation coefficient between X and Y is:

If, \(U = \frac{X-a}{h}\), \(V = \frac{Y-b}{k}\); \(a, b, h, k>0\), then \(b_{UV}\) is

The correlation coefficient between two variables X and Y is 0.60 and it is given that \(\sigma_X = 2, \sigma_Y = 4\). Then, the angle between two lines of regression, is
