One sample has SS = 48 and a second sample has SS = 32. When both samples have n =5, what is each sample varianceand computed pooled variance?
Then, if the first sample is n = 5 and the second is n = 9, what are the sample variances and the pooled variances?
The solution provides step by step method for the calculation of sample variances and pooled variance. Formula for the calculation and Interpretations of the results are also included.
