Variables sampling involves estimating characteristics of the population based on sample data. However, there is always a possibility that the sample is not representative of the population, resulting in estimates that are not close to actual population values. While confidence intervals can be calculated in variables sampling, they are affected by the sample size and the variability in the population. Therefore, option A is not correct. Option C is also not correct because the reliability of the statistical inference process can be assessed by evaluating the sampling plan and the sampling results.
