Reference no: EM131712831

One sample has SS= 36 and a second sample has SS= 18.

a. If n= 4 for both samples, find each of the sample variances and compute the pooled variance.

b. Now assume that n = 4 for the first sample and n = 7 for the second. Again, calculate the two sample variances and the pooled variance
