When using variable sampling, there is always a possibility that the sample is not sufficiently representative of the population to provide a sample mean or standard deviation reasonably close to those of the population. Therefore, drawing statistical inferences about the population using variable sampling methods may not necessarily give an accurate result. However, a confidence interval can still be calculated in variable sampling. Option A is incorrect. Option C is also incorrect because there are established procedures for calculating the reliability of statistical inference in variable sampling.
