One sample has n = 10 scores and a variance of s² = 20,and a second sample has n = 15 scores and a variance of s² = 30.What can you conclude about the pooled variance for these two samples? A)It will be closer to 20 than to 30. B)It will be closer to 30 than to 20. C)It will be exactly half way between 20 and 30. D)It will be equal to 25.

Since the sample with n=15 has a larger variance than the sample with n=10, it is likely that the pooled variance will be closer to the larger variance (30) than to the smaller variance (20). Therefore, the correct answer is B.

One Sample Has N = 10 Scores and a Variance
