Let SA2 = The sum for i=1 to 8 of (si-1.5125)2 = .10875, where Si is the ith sample from location A.
Let SB2 = The sum for i=1 to 6 of (si-1.5125)2 = .167673, where Si is the ith sample from location B.
Let U be the statistic for testing the the hypothesis that the mean of location A does not equal the mean of location B.
U = (sqr(8+6-2)*(1.5125-1.6683)) / (sqr(1/8 + 1/6)+sqr(.10875+.167673)) = -1.693354 .
The t value, with 12 degrees of freedom, at the .95 level of significance is 1.782 .
Thus if -1.782 <= U <= 1.782 the test will pass, which it does.
