Scenario 4 One sample has SS1=60 and a second sample has SS2=48. A) If n=10 for both samples, what would you expect the pooled variance would be compared to the two sample variances? a. The pooled variance would be exactly half way between the two sample variances. b. The pooled variance would be smaller than each sample variances. d. The pooled variance would be larger than each sample variances. B) Now assume n=10 for the first sample and n=7 for the second sample, what would you expect the pooled variance would be compared to the two sample variances? a. The pooled variance would be exactly half way between the two sample variances. b. The pooled variance would be closer to the larger sample's variance. c. The pooled variance would be closer to the smaller sample's variance.
