Final answer:
Without additional information about the criteria for receiving a $1000 raise, it is impossible to determine how many of the 200 students would receive $250 or more. Students with "A" grades might feel they deserve the raise but could also be demotivated, while those with "C" grades might be encouraged or become complacent based on the specifics of the raise.
Step-by-step explanation:
The question seems to be about a hypothetical scenario where students are discussing whether their class deserves a $1000 raise. When considering this scenario, students with "A" grades might feel that they deserve the raise due to their hard work and high achievement.
They might be concerned that the raise could diminish the value of their effort if it is given to everyone regardless of performance. As for their actions moving forward, these students might continue to work hard to ensure they maintain their top grades, or they might feel demotivated if the raise does not align with their perception of merit.
Regarding the question of how many students are expected to receive $250 or more from a sample of 200 students, we would need more data to determine this, such as the criteria for receiving this amount. Without this information, we cannot accurately calculate the number of students who would receive $250 or more, so the correct answer would be D. Cannot be determined.
For students with "C" grades before the change, the idea of getting a $1000 raise might be seen as a positive incentive. These students might feel encouraged to improve their grades, or they might become complacent if the raise does not require improved performance. Their actions moving forward would depend on the specifics of the raise conditions and their personal motivation.
