This statement is true. The paired t-test requires comparing two sets of paired data from the same sample, which results in a decreased degree of freedom. The formula for the degrees of freedom for a paired t-test is (n-1)/2, while for an independent t-test it is simply (n1 + n2 - 2). Therefore, the paired t has one-half the degrees of freedom of an independent t.
