Answer:
B. The height of all the students at West Middle school
Step-by-step explanation:
The greatest variability is a large spectrum of possibilities.
The costs of candy from a vending machine are all going to be about the same price because they are all candy, so that doesn't vary much.
The age of all the students in the sixth grade is going to be about the same because they are in the same grade.
The number of days in a month is usually 31 or 30, so that also does not vary much.
This means that it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.
