#16 once again referring to question #13 above, what is the 18% figure?
(a) a sample statistic
(b) a sample parameter
(c) a population statistic
(d) a population parameter
(e) none of the above

Explanation:

[#15]

A sample is a subset of the population that is actually studied. Here, the 500 students who were surveyed are the sample (they are the ones from whom data is collected), while the other options refer to populations (all students at a university, all nursing students at a university, all US college students, all US nursing college students).

A sample statistic is a measure calculated from a sample. The 18% is likely derived from the sample (the 500 surveyed students), so it's a sample statistic. A parameter is about the population, so B and D are wrong. "Population statistic" is not a standard term, so C is wrong.

Answer:

C. The 500 students who were surveyed
