Question: As noted on page 261, when the 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 two sample means. For each of the following situations, assume that u1 = u 2 and calculate how much difference should be expected between the two sample means.

1. One sample has n = 8 scores with SS 30 and the second sample has n 8 scores with SS 26.
2. One sample has n = 8 scores with SS 150 and the second sample has n = 4 scores with SS 90.
