6. two separate samples receive differently treatments. After treatment, the first sample has n = 9 with SS = 462, and the second has n = 7 with SS = 420. Please show all work!!! How you got your answers.

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 two-tailed test with a = .05?
