1. choosing an appropriate sample size is depends on A. the level of confidence desired B. the variability in the population being studied C. the maximum allowable error D. all of the above E. non off the above

D. all of the above

Explanation:

Choosing an appropriate sample size depends on all of the above factors.

For example, if we want a sample with a high level of confidence, for a population that is very diverse (high variability), and we want the sample to have a very low margin of error, we would need a large sample, in order to make the sample as close as possible to the population as a whole.
