How to compute the pvalue? Here is my working: null hypothesis : mean(d) > 0 alternative hypothesis : mean(d)≤ 0 Using paired ttest, I calculated the differences and got test statistic as 5.805, which is the right value. However, I am lost for computing the pvalue. I take it that this is a 1tail test. From the table provided, at df = 5, a = 0.05, critical value is 2.015. This means that 0.005 (4.032) <p < 0.0005 (6.869). Thus, I have to reject null hypothesis. But it doesn't make sense, I know I do not reject it. May I ask where did I go wrong in calculating my p value? I know it has to be greater than 0.05. Any help is appreciated!
