Answer to Question #46486 in Statistics and Probability for Anurodh
Question #46486
In order to find the correlation coefficient between two variables X and Y
from 20 pairs of observations, the following calculations were made:
Σx =15, Σy = − 6, Σxy = 50, Σx^2 = 61 and Σy^2 = 90 .
Calculate the correlation coefficient, and the slope of the regression line of Y on X.
