The remaining students are 70 if the mean quiz score for 8 students is 50.
What is mean?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
Mean = Sum of all observation/Number of observation.
The Sum of scores (if observation is 3) = 20×3 = 60
The Sum of scores (if observation is 1) = 30×1 = 30
The Sum of scores (if observation is 3) = 80×3 = 240
Total sum of the students = 60+30+240 = 330
The mean quiz score for 8 students is 50
The sum of students = 50×8 = 400
Remaining students = 400 - 330 = 70 students
Thus, the remaining students are 70 if the mean quiz score for 8 students is 50.
