Answer:
0-16
Explanation:
since it tells you 4 students does homework does more then one hour and 20 students were questions there is a chance that the other students who answered will take less time. A mode is when one number appears the most in your case it’s the number of students that appears the most in you line plot. Example: 2 students take one hour (put 2 dot on one) 5 students take 2 hours (put 5 dot on two hour) and 1 student takes 2.5 hours (put a dot on 2.5) then the mode for this example the mode is 5
hope this helps and it’s understandable I honestly don’t know if I explain it well. Your case the number could be 0-16 make a plot and I can help (add me as a friend)
