Question

question 4
when estimating the percentage of college students who apply to graduate school, a researcher reports a margin of error. what does the margin of error reflect?
the inclination of students to decline to answer survey questions.
the natural differences that wed expect to arise from sample to sample.
the possibility that some students will provide inaccurate information.
the fact that certain students were not included at all in the sample.
all possible sources of bias from both sampling and nonsampling issues.

Explanation:

The margin of error in sampling reflects the natural variability that occurs due to the fact that different samples from the same population will yield different results. It is not about non - response bias (students declining to answer), response inaccuracy, sample exclusion, or all possible biases. It simply accounts for the random differences between samples.

Answer:

The natural differences that we'd expect to arise from sample to sample.
