Paired t-Test 2. If n, = n2 = n and if the pairs of values of *, and x, are associated in some way (or correlated), the formula (2) fort in Note (1) should not be used. In this case, we shall assume that Ho : d = x - y) = 0 and test the significance of the difference between ) and 0, using the test statisticht = with v = n -- 1, where d, = x,-; (i = 1, 2, ..., s/n.-1 d M m), 7 = 3 – 5; and s= S.D. of d's="? Ś(d,-a)? $
