• Two separate samples are selected from the same population. Each have an n=8. Both samples receive a different treatment. After the treatment, the first sample has SS=16 and the second sample has SS=24.

1. Using symbols, state the hypotheses for a two-tailed test.

2. With a two-tail α=0.05, identify the degrees of freedom and the critical regions.

3. Calculate the pooled variance
