Question

If a sample of 14 students were taken from a population of 168 students, o?

could refer to the variance of how many of the students' heights?
A. 168
B. 14
C. Both 14 and 168
D. Neither 14 nor 168

Answer 1

The variance refers to the spread or variability of a set of data. In this case, the variance of the heights of the students in a sample of 14 students would represent the variability in their heights.

Step-by-step explanation:

The statement is asking which value, 14 or 168, could refer to the variance of how many of the students' heights. The variance represents the spread or variability of a set of data. In this case, the heights of the students are being considered.

Since the sample consists of 14 students, the variance would represent the variability in the heights of those 14 students. Therefore, the answer is B. 14. The variance does not take into account the entire population of 168 students.
