The correct answer to the given question is option d. Statistical inference.
In order to facilitate statistical analysis for a large population, a small representative sample is usually drawn from it and then statistical parameters such as mean and standard deviation are determined. A hypothesis testing is usually then carried to see whether the sample results can be applied to the population. Such analysis is called as statistical inference or inferential analysis.
