Question
A.)
One sample (n1) has SS = 70 and a second sample (n2) has SS = 42.
1. Find the sample variance for n1, if n1= 8
2. Find the sample variance for n2, if n2 = 8
3. Calculate the pooled variance for both samples
4. Due to the fact that these samples are the same size, what is true about the calculated pool variance
