Question: Assuming equal population variances, compute the pooled sample variance s2p for part a through part c of Exercise 8.8. In exercise a. nx = 16

Assuming equal population variances, compute the pooled sample variance s2p for part a through part c of Exercise 8.8.
In exercise
a. nx = 16 s2x = 30
ny = 9 s2y = 36
b. nx = 12 s2x = 30
ny = 14 s2y = 36
c. nx = 20 s2x = 16
ny = 8 s2y = 25
