Answer:

B. NON-REPRESENTATIVE

Step-by-step explanation:

<em>The sample does not represent the population as a researcher is taking a sample from the hospital where the cholesterol level of the patient is generally high and the researcher is not randomly selecting the U.S. citizens.</em>

Thus, option (B) is correct.

Further, the sample is a subset of the population and it is easy to analyze as compared to the population.

The sample is said to be representative if it represents the whole population.
