Researcher Smith conducts a study and is NOT able to reject the null hypothesis. We would interpret this as meaning that any observed mean group difference was probably due to

Sampling error

Explanation:

This is probably due to sampling error. The sampling error has the likelihood of occuring when the statistician fails to select a sample that could be a representation of the full population. The sample results are not a true representation of the true results from the entire population.

the null hypothesis tells us that no significant difference exists between the populations chosen, and any difference can be as a result of sampling error.
