Answer
We know that the population is a set of all elements and sample includes some or all those of elements, but sample never includes more elements as compared to population.
We select sample from the population.
In this case, Survey include 128 DeVry statistics students, so these 128 statistics students is a sample and total number of Devry statistics students will be the population. 83% is sample statistic, i.e. it gives us numerical information about the sample.
So, population is DeVry statistics students and sample is 128 DeVry statistics students.
Option C is correct.
