Question

false :
(i) The correlation coefficient between x and y is 0.78, hend
correlation coefficient between - x and -y is - 0.78
(ii) If the points of the scatter diagram are not in a straight
they indicate absence of the relationship.
(iii) If Ed? = 0 then there is no correlation between the
variables.
(iv) The correlation coefficient 0.6 indicates twice the relatic
than the correlation coefficient 0.3.
(v) If two variables are independent then r = 0.​
