... probabilities, it can be determined that combining the probability values of 0.11 and 0.07 results in a probability value of 0.045. Therefore, these two nonsignificant findings taken together result in a significant finding. Although there is never a statistical basis for concluding that an effect i ...

In this case, 3 units of about 3 would mean that sample means (when n = 9 from this population) would not be expected to vary by more than approximately 9 or 10 points on either side of the population ...
