A sample A. Is part of the population. B. Has more

This answer was rated:

A sample

A. Is part of the population.
B. Has more than 30 observations.
C. Is usually identified as N.
D. All of these
That's A., part of the population.

Part of the whole point of the science of statistics, the idea is to make reasonably reliable conclusions about a population without measuring every single member of that population (whether animal, vegetable or mineral or numeric).

The multiple-choice falls apart with choice B, more than 30 observations or measurements. A *good* sample, one that is more reliable, starts in many opinions at 30 measurements (the t-test is implicated here) for large populations.
