  1. an independent measures study with n=6, produces a sample mean difference of 4 points and a pooled variance of 12. what is the t statistic Solution You're given the pooled variance Vp=12, which means you're assuming that the population variances V1,V2 for the two statistics are equal. By making that assumption, t = [(M1 - M2) - (u1 - u2)]/sqrt(Vp/n1 + Vp/n2)
