Question: As noted, when two population means are equal, the estimated standard error for the independent measures t-test provides a measure of how much difference to expect between the two sample means. For the following situations, assume that \({{\mu }_{1}}={{\mu }_{2}}\) and calculated how much difference should be expected between the two sample means.

(a) One sample has n = 8 scores with SS = 30 and the second sample has n = 8 scores with SS = 26.

(b) One sample has n = 8 scores with SS = 150 and the second sample has n = 4 scores with SS = 90.
