Two separate samples receive different treatments. After treatment, the first sample has n = 5 with SS

Question:

Two separate samples receive different treatments. After treatment, the first sample has n = 5 with SS = 60, and the second has n = 9 with SS = 84.

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 7 points, is this enough to reject the null hypothesis using a twotailed test with α = .05?
