Question 7 1 pts 7. An independent-measures research study uses two samples, each with n = 10, to compare two treatments. If the results are evaluated with a t statistic using a two-tailed test with a = .05, then the critical region would have boundaries of. O t = 2.262 O t = 2.086 O t = 2.093 O t = 2.101 Question 8 8. Two samples, each with n = 6 subjects, produce a pooled variance of 20. Based on this information, the estimated standard error for the sample mean difference would be O (20/5+20/5) 20/12 20/6 O (20/6+20/6) 1 pts
