One sample has s² = 12,and a second sample has s² = 15.The pooled variance for these two samples will be between 12 and 15.

Question

Quizplus · Accepted Answer

This statement is true as the pooled variance is calculated by combining the variances from each sample and weighting them based on their sample size. Since the second sample has a larger value for s², it is likely to have a larger variance, therefore the pooled variance would fall between 12 and 15.
