10. Two separate samples receive two different treatments.

The first sample has n  9 with SS  710, and the second has n  6 with SS  460.

a. Compute the pooled variance for the two samples.

b. Calculate the estimated standard error for the sample mean difference.

c. If the sample mean difference is 10 points, is this enough to reject the null hypothesis using a twotailed test with .05?

d. If the sample mean difference is 13 points, is this enough to reject the null hypothesis using a twotailed test with  .05?
