What is statistical inference?
A) a way to infer conclusions about the wider population from sample data B) using facts about a sample to estimate the truth about the whole population C) a way to describe the uncertainty and variability inherent in all statistical information D) all of the above
D) all of the above
Explanation:
We know that the statistic inference is the statistical technique regarding the inference about population parameters by using the sample statistics. We use the sample statistics for making the conclusions about the population. By using different types of hypothesis tests or non-parametric tests we make conclusions about the populations. For understanding the truth about the population, we need to use sample data and check the facts about sample and then we generalize this information for the population. We know that the statistical inference is dealing with the variability in the statistical information.
