Answer to Question 1

The study is observational. The statistics practitioner did not randomly assign stores to selling bottles or cans. Type of store and type of packaging cannot be separated here.

Answer to Question 2

Advantages: It is an inexpensive method of conducting a survey, since it is usually mailed to a sample of people, and is therefore attractive when the number of people to be surveyed is large.

Disadvantages: Self-administered surveys usually have low response rates and may have a relatively high number of incorrect responses due to respondents misunderstanding some questions.
