not sure how to do this

1. Let's say we have two samples. One has SS = 36 and a second sample has SS = 24. (5 points total; 2.5 points each) a. If n = 5 for both samples, compute the pooled variance. Show your work or explain your answer. (2.5 points) (HINT: Because the samples are the same size, you should find that the pooled variance is exactly halfway between the two sample variances.) - b. Now assume that n = 5 for the first sample and n = 13 for the second. Again, calculate the pooled variance. Show your work or explain your answer (2.5 points) (HINT: You should find that the pooled variance is closer to the variance for the larger sample.)
