Question

select the correct answer from each drop - down menu.
a restaurant is analyzing its customer satisfaction level. the manager performs an observational study of customers during the lunch hour on a monday and draws the conclusion that most of the customers are satisfied with the service they receive.
the conclusion drawn from the study is
because the sample is
. in this instance, an
study was conducted.

Explanation:

To solve this, we analyze the context of the study:

First Dropdown (Conclusion Validity):

The study uses a sample (customers during Monday lunch). If the sample is not representative (e.g., only Monday lunch customers, not all customers), the conclusion “most customers are satisfied” is not valid (or “unreliable”) because the sample may not reflect the entire customer population.

Second Dropdown (Sample Type):

The sample includes only customers during Monday lunch, so it is not representative (or “biased”)—it does not include customers from other days/times, so it may not represent all customers.

Third Dropdown (Study Type):

The manager observes customers (does not manipulate variables) to draw conclusions, so it is an observational study (no experiment, just observation of existing behavior).

Final Answers (Typical Correct Selections):

1. The conclusion drawn from the study is \(\boldsymbol{\text{not valid}}\) (or “unreliable”).
2. because the sample is \(\boldsymbol{\text{not representative}}\) (or “biased”).
3. In this instance, an \(\boldsymbol{\text{observational}}\) study was conducted.

(Note: Exact wording depends on dropdown options, but the logic is about sample representativeness and study type.)
