If u + 5x = 6 and 3y - 7v = 20 and the correlation coefficient between x and y is 0.58 then whatwould be the correlation coefficient between u and v?(a) 0.58(b) -0.58(c) -0.84(d) 0.84 |

Answer» Answer: B)-0.58 Step-by-step EXPLANATION: As CORRELATION COEFFICIENT is unaffected by change of SCALE and origin the absolute value of 'r' will not change . Whereas sign will change as sign of scales are different. I.e -5 and 3/7 from :- u=6-5x and v=3/7y-20 |
