Answer 1

Answer #1

ss=24

answered by: ratios

Answer 2

Answer #2

one sample has ss=36 and a second sample has ss=18 If n=4 for both samples, find each of the sample variances and compute the pooled variance. Because the samples are the same size, you should find that the pooled variance is exactly halfway between the two sample variances. The first sample has ________ (choose one of the following 12.00, 9.00, 6.00, 3.00), and the second has s^2=______((choose one of the folloeing 12.00, 6.00, 3.00, 4.50). The pooled variance is s^2p=________(9.00,...
