The study has high internal validity because it has a significant result (p-value of .001) and has ruled out alternative hypotheses, indicating that the study was well-controlled and the results are likely due to the variables being tested. However, it has low external validity because the results cannot be generalized to real-life settings, meaning the findings may not apply outside of the study's specific conditions.
