If the mean difference between two independent groups of 12 participants each is 8.00 and the estimated standard error of the sampling distribution of differences between means is 4.00 (t-critical = 2.074 for 22 df), what is the 95% confidence interval and should we retain or reject H0? -0.3 to 16.3; retain H0 -0.3 to 16.3; reject H0 0.44 to 20.44; reject H0 0.3 to 16.3; reject H0
