is this study
a. representative?
b. non-representative?

Non representative

Step-by-step explanation:

A representative sample would be a subset of a population that accurately describes some characteristic from a larger group of people.

A sample of 40 patients from a local hospital is not a big enough sample to estimate the mean cholesterol level of U.S citizens (citizens from an entire country).

Therefore, this sample would be non representative.
