C ) No, bc not all students in da sample have extracurricular activities

D ) Yes, bc every student shad an equal chance 2 b part of da sample. Da sample size also appears 2 b large ENUFF

Answer 1

The correct answer is:

C) No, bc not all students in da sample have extracurricular activities.

The principal's conclusion is not valid because the sample may not represent the entire population of students. If the sample only includes students with extracurricular activities, it doesn't accurately reflect the average number of activities for all students, including those who do not participate in any activities at all. Thus, the sample could bias the average upward.
