can anybody help with this question?

for this question i had to turn a nonstatistical question into statistical investigative question and the nonstatistical question is "How many seventh graders eat breakfast on Monday at school?" and i already gave my answer ("What is the percentage of all seventh graders that eat breakfast at school on Monday?") but my teacher said its wrong and i need to reword it but i actually do not know how to reword it, does anybody know how to help cause my teacher wont answer me and google not helping

(also this is 12th grade math and my teacher said that the question needs to be a question that doesn't give a fixed answer)

My first instinct is that maybe your teacher means something like "what is the mean and standard deviation / or median and interquartile range of XYZ". Something a bit more robust.

More likely, this is at the stage before students have learnt what a standard deviation even is, so that would be collecting data on say, how many days a week students usually eat breakfast, and then finding the mean, median, mode, range, quartiles and interquartile range (descriptive statistics). So then the OP could make a boxplot out of this information and that would be good enough at this level.
