Final answer:
States that require physical education courses are associated with improved academic performance due to the beneficial effects of physical activity on concentration, memory, and classroom behavior.
Step-by-step explanation:
The question asks which of the following is true about states that require physical education courses. The most accurate statement is that states that require physical education courses show improved academic performance. Research indicates that physical activity can have a positive effect on academic achievement, as it helps improve concentration, memory, and classroom behavior. Physical education may also foster a competitive nature and enhance students' efforts in their schoolwork, contributing to an overall beneficial impact on academic performance.
Assumptions such as states with physical education having higher dropout rates or shorter school days are not backed by evidence and therefore are not true. Furthermore, it is not evident that physical education requirements directly affect student attendance negatively. In contrast, it is noted that engagement in activities, including athletics, may relate to higher attendance and lower class withdrawal rates.
Thus, Option 2, states that require physical education courses show improved academic performance, is supported by evidence and experience from various studies on the matter.
