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 \({{\mu }_{1}}={{\mu }_{2}}\) and calculate 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 = \(90\).
