No, his sample is not random. Since the principal only surveyed students as they arrived at school, it is likely that not all 7th graders were included in the survey, leading to potential bias in the results. Random sampling involves giving every member of the population an equal chance of being selected for the sample.

Yes, I am sure. In order for a sample to be considered random, every member of the population should have an equal chance of being selected for the sample. Surveying students only as they arrived at school may not capture all the 7th graders in the school, leading to potential bias in the results. So, this sample is not random.
