Answer:
2
Explanation:
There are 5 people with no siblings, 4 people with 1 sibling, 1 person with 2 siblings, 1 person with 3 siblings, 2 people with 4 siblings, and 3 people with 5 siblings.
You add up all the siblings: 0(5)+1(4)+2(1)+3(1)+4(2)+5(3)
Which equals 32 siblings in total.
A total of 16 students were surveyed. So now you divide the total number of siblings by the total number of students: 32/16
Which comes out to be 2.
The mean of siblings is 2.
Hope that helps!
