Answer: 3.19
--------------------------------------
Explanation:
S = sum of the siblings
Dividing this sum over the 25 students will give us the average of 3, so, S/25 = 3 which turns into S = 75 when we multiply both sides by 25.
S = 75 means adding up all of the students' sibling counts gets to 75 total.
A new student has 8 siblings, so the total goes to S+8 = 75+8 = 83
Divide this over the new count of 26 to get 83/26 = 3.1923076923077
this rounds to 3.19
