One sample has SS 36 and a second sample has SS 24 If n7 f

One sample has SS = 36, and a second sample has SS = 24 If n=7 for both samples, find each of the sample variances and compute the pooled variance.

Variance of first sample? Variance of second sample? Pooled variance?

Because the samples are the same size, the pooled variance is: A) closer to the second sample variance B) closer to the first sample variance C) Exactly halfway between the two sample variances

Now assume that n=7 for the first sample and n = 13 for the second. Again, calculate the two sample variances and the pooled variances (use two decimal places, if needed)

Variance of first sample? Variance of second sample? Pooled variance?

The pooled variance is: A) exactly halfway between the two sample variances B) closer to the variance for the larger sample C)closer to the variance for the smaller sample
