(i) For how many hours did the maximum number of students watch TV?
(ii) How many students watched TV for less than 4 hours.
(iii) How many students spent more than 5 hours in watching TV.

Answer 1

(i) Since the bar 4-5 is highest,
Therefore, maximum students watch TV for less than 4-5 hours.

(ii)Number of students watch TV for less than 4 hours = Number of students watched TV for 1-2 hours + Number of students watched TV for 2-3 hours + Number of students watched TV for 3-4 hours.
= 4+8+22
=34 Students.

(iii)Number of students watch TV for more than 5 hours = Number of students watched TV for 5-6 hours + Number of students watched TV for 6-7 hours.
= 8+6
= 14 Students.
