In Q.3 part (a) we have to take class intervals as 0-2,2-4, etc. While making a frequency table, where does the number 2 go? In class interval 0-2 or 2-4 ?

Q. 3 Each of the 25 students in a class was given a home assignment comprising 10 questions in mathematics. The data given below show the number of questions solved and submitted by individual students on the next day.

1, 4, 5, 6, 0, 9, 3, 2, 3, 4, 6, 4, 5, 2, 7, 5, 2, 2, 3, 5, 1, 0, 7, 6, 3

(a) Taking classes as 0-2, 2-4, 4-6, etc., make a frequency table for the above distribution.
