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 not valid/valid because the sample is biased/unbiased. in this instance, an inappropriate/appropriate study was conducted.

Explanation:

Analyze the validity of the conclusion

The study only observes customers during the lunch hour on a single Monday. This specific, narrow time frame does not represent the entire customer population (e.g., dinner customers, weekend customers), making the sample biased and the overall conclusion not valid.

Evaluate the study design

An observational study is conducted by observing subjects without manipulating any variables. While an observational study is a legitimate statistical method, using a highly restricted sample (only Monday lunch hour) to generalize about overall customer satisfaction is inappropriate.
