<h3><u>
Answer:</u></h3>
Hence, the number of students watching TV 3 hours or less are:
13
<h3><u>
Step-by-step explanation:</u></h3>
From the dot plot we can represent a set of data values in a table as:
Number of hours Frequency
0 5
1 5
2 1
3 2
4 1
5 4
6 2
7 0
Here frequency represent the number of students watching tv at the number of hours.
Now the number of students watching TV 3 hours or less is:
5+5+1+2=13.
Hence, the number of students watching TV 3 hours or less are:
13
