Full solution

Q. Sidney interviewed

25

students in each grade. Each grade has an equal number of students.

\newline

Is this sample of the students in the school likely to be representative?

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Understand Sampling Method: Understand the sampling method. $\newline$ Sidney interviewed $25$ students from each grade, with each grade having an equal number of students.
Analyze Representativeness: Analyze the representativeness of the sample. If each grade has an equal number of students and the same number of students from each grade were interviewed, the sample should represent the student body proportionally across grades.
Consider Other Factors: Consider other factors that might affect representativeness. Factors like diversity in ethnicity, gender, or academic performance aren't mentioned. However, the question focuses on grade representation, which seems to be addressed.
