Question 1. One sample has n = 5 scores and the second has n = 10 scores. If the pooled variance for the two samples is 30, what is the value of the estimated standard error for the sample mean difference?
Question 2. Two samples, each with n = 9 scores, produce an independent-measures t statistic of t = 2.00. If the effect size is measures using r^2, what is the value of r^2?
