Hi

May I have the clarification for the following question?

In the “Scores” dataset, we had 15 students who had scored below the class average in a group of 30 students. If we generalize it to a group of NN students, how many students would be below the class average?

How is it not N/2, According to the Given question data?. Because when we generalize it to a group of N students and if that is the question then it is right to say as insufficient data but according to that data, It would turn out to be N/2 as it suits that right?.

Regards,

Shyam.

If it is generalized to N how can it be N/2?

>In the “Scores” dataset, we had 15 students who had scored below the class average in a group of 30 students. 

If we take the 30 students as N, then the N/2 becomes correct.

Please correct me if I am wrong

Generalization should stand true even if I modify the values on the dataset. When we are trying to generalize for a group of N students we don't know if it will stand true. It depends on the dataset. It might be or it might not be. Even for the given dataset if I alter the scores no of students below avg may no longer be 15.

Hi,

Average can not be generalized unless we do not know the values of dataset. Since we don't know the scores of N students so we can not find the average. Therefore the answer will be "Insufficient data".
