Answer 1

To determine if each approach will result in a sample that is representative of the population, we need to consider if the sample will include a diverse and accurate representation of the population.

Step-by-step explanation:

To determine if each approach will result in a sample that is representative of the population, we need to consider if the sample will include a diverse and accurate representation of the population. Let's analyze each approach:

Surveying all of the flute players in the band: This approach may not be representative of the entire band since it only focuses on one instrument. It does not include the opinions or experiences of other band members.

Surveying all band members whose first names start with J or M: This approach may result in a biased sample since it only includes band members with specific initials. It may not accurately represent the entire band.

Surveying two band members from each school in her city: This approach has the potential to be representative of the population as it considers band members from different schools. It includes a diverse range of students and may provide a more accurate representation of the overall population.

Answer 2

Option C would be better than the others.

Step-by-step explanation:

She wants to learn about band members from a sample of the population. Option a isn't enough because flute players aren't the only ones who should be surveyed, she needs to know about all band members. B isn't right, it isn't logical to just survey people with names starting with J or M. So, c would be just right since she's surveying 2 band members from each school so she would get information from a sample of the population and not just from her school.
