Question

A survey of 1205 physicians found that about 60% considered leaving the practice of medicine because they were discouraged over the state of U.S. health care.

What’s the population and what’s the sample?
A. Population: All physicians; Sample: 1205 physicians
B. Population: 1205 physicians; Sample: All physicians
C. Population: Discouraged physicians; Sample: All physicians
D. Population: U.S. health care practitioners; Sample: 1205 physicians

Answer 1

The correct answer is A. Population: All physicians; Sample: 1205 physicians, since the population is all physicians and the survey included 1205 physicians.

Step-by-step explanation:

The question concerns the identification of the population and the sample in a statistical study about physicians' attitudes toward the state of U.S. health care. In this context, the population is the larger group to which we would like to generalize our findings, while the sample is the subset of the population that is actually surveyed or studied. Based on the information provided, the correct answer is A. Population: All physicians; Sample: 1205 physicians.

This is because the population of interest is all physicians, and the survey only includes a portion of this group, specifically the 1205 physicians who were surveyed. The provided survey data could then be used to make inferences about the larger population of physicians.
