Question

question 3 of 6, step 1 of 1
determine whether an observational or experimental study is appropriate to address the following statement.
a deli cart entrepreneur wants to find out if her customer base is shrinking.

Explanation:

To determine if the customer base is shrinking, an observational study is appropriate. In an observational study, we observe and collect data without interfering. Here, the entrepreneur can collect data on customer visits, sales, or use surveys over time to see trends. An experimental study would involve manipulating variables (like changing prices, menu), but here we just need to observe the existing customer base trend, so observational study is suitable.

Answer:

Observational study (since we just observe customer base trends without manipulating variables; we can collect data on customer frequency, sales, etc. over time to assess if the base is shrinking).
