4. One sample has SS = 80 and a second sample has SS = 48. a. If n = 17 for both samples, find each of the sample of the variances, and calculate the pooled variance. Der Because the samples are the same size, you should 45773 Source: SPSS@ find that the pooled variance is exactly halfway 15773 between the two sample variances. b. Now assume that n = 17 for the first sample and aries n = 5 for the second. Again, calculate the two and sample variances and the pooled variance. You will should find that the pooled variance is closer to the Use a tive variance for the larger sample. two-to the 5. Two sends
