Question
Each sample has n= 5 scores with s2 =38 for the first sample and s2 = 42 for the second. (Note:
Because the two samples are the same size, the pooled variance is equal to the average of the
two sample variances.)calculate how much difference should be expected, on average, between the two sample means
