    One sample has SS = 48 and a second sample has SS = 42
    a. Assuming that n = 4 for both samples. Find each of the sample variances, and calculate the pooled variance. You should find that the pooled variance is exactly halfway between the two sample variances.
    b. Now assume that n = 4 for the first sample and (n = 8 for the second. Find each of the sample variances, and calculate the pooled variance. You should find that the pooled variance is closer to the variance for the larger sample (n = 8).

Sample mean [ 1 Answers ]

If 40 samples, each of size n=21, were selected from a population of 22,493, we would expect the mean of the sample means and the population mean to be close but not exactly equal. Is this statement true or false? I said it was true, is that correct?
