Answer 1a and 1b 1a.) The benefit of using probability sampling over nonprobability sampling: Choose below:  The reliability of estimators in nonprobability sampling CANNOT be computed. Probability sampling assures having estimators that are reliable or precise. Probability sampling assures having estimators that are not biased or unbiased. In general, nonprobability sampling entails more transportation and listing costs. 1b.) If there are 100 elements in the population, and a sample of 20 is to be selected using systematic sampling. Identify the sampling interval. Choose below:  5 1/5 20 2,000
