However, overlap (or non-overlap) of standard errors or confidence intervals is not usually a valid hypothesis test--so it is premature to assert there's any kind of "contradiction." See stats.stackexchange.com/questions/31657 and stats.stackexchange.com/questions/18215, for instance. | |

| Feb 7, 2017 at 20:57 | comment | added | Carlamarita Hazelgrove | I calculated the standard errors and t test on an online programme! I determined the t test result to be significant as the t statistic was greater than the critical value! The level of significance was P<0.05. | |
| Feb 7, 2017 at 20:55 | comment | added | whuber♦ | Please show us the details: how were the standard errors computed, how was the t-test conducted, and how have you determined that the t-test result is not significant and at what level of significance? | |
