The marks obtained by 40 students of class VIII in an examination are as under.
24, 3, 11, 18, 13, 10, 8, 1, 6, 4, 6, 17, 9, 7, 13, 9, 19, 13, 6, 24, 3, 17, 24, 20, 16, 14, 22, 14, 2, 8, 22, 9, 14, 19, 25, 8, 4, 19, 18, 17
The teacher asked the students to arrange the data in a grouped tabular form by dividing the data into convenient class intervals, say, 0-5, 5-10, etc.
1. How many class intervals are formed?
(a) 4$\quad$(b) 5$\quad$(c) 6$\quad$(d) 7$\quad$
2. The range of the given data is
(a) 22$\quad$(b) 23$\quad$(c) 24$\quad$(d) 25$\quad$
3. Which class interval depicts the highest frequency?
(a) 5-10$\quad$(b) 10-15$\quad$(c) 15-20$\quad$(d) 20-25$\quad$
4. The frequency corresponding to the class interval having the least frequency is
(a) 1$\quad$(b) 6$\quad$(c) 7$\quad$(d) 8$\quad$
