Question
We have 2 samples from 2 populations with information x1 = 7.2, s1 = 2, n1 = 9; x2 = 9.0, s2 = 4, n2
We have 2 samples from 2 populations with information x1 = 7.2, s1 = 2, n1 = 9; x2 = 9.0,
s2 = 4, n2 = 16;
If we assume 12 = 22
Find an estimate s2p of the common variance i.e. Find pooled variance
