Q. The school board administered a reading test to all eighth-grade students at High Achievers Charter School and determined that

10 \%

of them were reading below grade level.

\newline

Based on this data, which of the following conclusions are valid?

\newline

Choose

1

answer:

\newline

(A)

10 \%

of all eighth-grade students at HACS are reading below grade level.

\newline

(B)

\mathbf{1 0 \%}

of all students at HACS are reading below grade level.

\newline

(C)

\mathbf{1 0 \%}

of students in this sample are reading below grade level, but we cannot conclude anything about the eighth-grade students at HACS.

Read Problem: Read the problem and understand what's being asked. $\newline$ The school board says $10\%$ of eighth-grade students at High Achievers Charter School (HACS) are reading below grade level.
Identify Conclusion: Identify the correct conclusion based on the given data. $\newline$ The data specifically mentions ＂eighth-grade students at HACS,＂ not all students at HACS.
Analyze Choices: Analyze the answer choices. $\newline$ (A) Matches the data given, as it specifies ＂eighth-grade students at HACS.＂ $\newline$ (B) Is too broad because it includes all students, not just eighth-graders. $\newline$ (C) Is incorrect because it suggests we cannot conclude anything about the eighth-grade students at HACS, which contradicts the data provided.
Choose Correct Answer: Choose the correct answer based on the analysis. $\newline$ The correct answer is (A) because it directly reflects the information provided by the school board.
