ine an 3. One sample has SS = 72 and a second sample has cts, research SS = 24. a. If n = 7 for both samples, find each of the sample variances and compute the pooled variance. Be- standard cause the samples are the same size, you should ures t find that the pooled variance is exactly halfway between the two sample variances.b. Now assume that n = 7 for the first sample and gra n = 11 for the second. Again, calculate the two foll sample variances and the pooled variance. You should find that the pooled variance is closer to the variance for the larger sample
