Short Answer

Expert verified

Systematic sampling should be used to estimate the average number of cans of soda consumed each month by students in their twenties at a school.

As a result, balanced student selection is critical. Following the selection of students from each stream, the number of soda cans consumed by each of them in a month is recorded in order to determine the mean number of soda cans consumed each month.
