Answer:
A t-test is a statistical test that is used to determine whether there is a significant difference between the means of two groups. If the t-test shows that the results are not statistically significant, it means that there is not a significant difference between the means of the two groups. This could be due to a variety of factors, including small sample size, high variance within the groups, or a lack of a real difference between the groups. It is important to interpret the results of a t-test in the context of the research question being asked and the limitations of the study.
