Tom wants to know the average number of musical instruments students in his school play. He use the school two band classes consisting of a total of 48 students as his representative sample. He concluded that students in his school playing average of three musical instruments is his conclusion valid, would it be no because his representative sample is too large or yes, because the sample includes both males and females who play musical instruments or no because he did not choose students randomly or yes, because all members of the sample play at at least one musical instrument

Answer 1

No, because his representative sample is too large. A sample size of 48 students is actually quite small for determining the average number of musical instruments played by students in an entire school. A larger sample size would provide a more accurate representation of the school population.
