For each of the following, calculate the pooled variance and the estimated standard error for the sample mean difference


a. The first sample has n = 4 scores and a variance of s2
= 17, and the second sample has n = 8 scores and a variance of s2
= 27.


b. Now the sample variances are increased so that the first sample has n = 4 scores and a variance of s2
= 68, and the second sample has n = 8 scores and a variance of s2
= 108.


c. Comparing your answers for Parts a and b, how does increased variance influence the size of the estimated standard error?
