Answer 1

I believe its B. Stratified because the owner had to speak to ten individuals, meaning he divided it into smaller groups.

Answer 2

b) Stratified

Explanation:

Given: A mattress store boasts 4 out 5 sleepers in a commercial that airs locally. I talked to the owner and found out he only talked to ten people.

This is not regressive as regressive got two variables dependent and independent

This is not variation as no variation is explained in the sample

This is not replication, as replication involves repitition of experiments a number of times.

This is not blocking because nothing is blocked in this

So this comes under

b) Stratified
