Final answer:
To determine the number of students expected to receive $250 or more, we need to calculate the percentage first. If the percentage is not given, we cannot determine the exact number.
Step-by-step explanation:
To determine the number of students expected to receive $250 or more, we need to calculate the proportion of students who fall within that range. Assuming a sample of 200 students, we can use a cumulative frequency distribution to find the cumulative frequency up to $250 and subtract it from the total number of students. If the percentage of students who receive $250 or more is not given, we cannot determine the exact number and the answer is D. Cannot be determined.
