Answer

Brief Explanations:

Diego sampled students only from band practice. These students are more likely to plan to go to a school - band concert compared to the general student population. So, the sample is likely to be biased and probably invalid as it doesn't represent all students in the school. It is not a random sample since it's not selected from the entire student body in a random way.
