Question

dallas wants to know what elective subjects the students at his school like best. he surveys students who are leaving band class. is this a random or biased sample, and why? it is a (select) ▾ sample because (select)

Explanation:

Dallas surveys only students in band class. A biased sample is one where the sample group is not representative of the entire population (all students in the school). Since band class students may have different elective preferences (e.g., more likely to favor music - related electives) compared to all students, this sample is biased as it doesn't randomly include all types of students.

Answer:

It is a biased sample because the sample only includes students from band class, which is not representative of all students in the school (different groups of students may have different elective preferences, and this sample excludes non - band - class students, so it doesn't give a fair representation of the entire student population's elective preferences).
