# Question: Assuming equal population variances compute the pooled sample variance s2p

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
