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. Compute the pooled variance for the two samples. Calculate the estimated standard error for the sample mean difference. If the sample mean difference is 7 points, is this enough to reject the null hypothesis using a two-tailed test with α = .05?
