Suppose x is a variable on each of two populations whose members can be paired and that a paired difference is the difference between the values of the variable x on the members of a pair.True or false? The mean of the paired differences equals the difference between the two population means.

B)True

The mean of the paired differences represents the average difference between the values of the variable x within pairs, while the difference between the two population means reflects the average difference in the values of x between the two populations as a whole. These two concepts are not equivalent, so they cannot be equal. Therefore, the statement is false.
