Textbook Problem

One sample from an independent-measures study has *n* = 4 with *SS* = 100. The other sample has *n* = 8 and *SS* = 140.

a. Compute the pooled variance. (*Note:* Equation 10.2 works well with these data.)

b. Compute the estimated standard error for the mean difference.

**a.**

To determine

**To compute:** The pooled variance for the given question.

Explanation

**Given info:**

The samples of size 4 and 8 have sum of squared errors (SS) of 100 and 140.
