Recently, the Grade 7 mathematics teacher noticed a concerning change in student performance. Section A, whose students had almost the same math grades as Section B in the previous quarter, received noticeably lower math grades this quarter. Meanwhile, students in Section B generally appear less tired and more attentive during class discussions.[br][br]The math teacher wonders whether sleep habits could be affecting students’ academic performance.

After collecting the data on daily sleeping hours, the teacher wants to:[br][br]1. Determine the typical number of hours students sleep in each section.[br][br]2. Compare the sleeping habits of Section A and Section B.[br][br]3. Analyze and interpret the results. Then, write a conclusion and recommendation based on the findings.
