Learning Outcomes

1	Understand required definitions for statistical inference, (Difference of population and sample concepts, definition of parameter)
2	Define the concepts of statistics and estimator (point estimator, interval estimator)
3	Apply estimating methods (moments, least squares, maximum likelihood, bayes estimation methods)
4	Expresses the required characteristics (unbiasedness, consistency, efficiency, sufficiency, minimum variance, etc.) sought in the estimators
5	Obtain interval estimate for the population parameter (parameters)
6	The hypothesis testing in accordance with the theory of the parametric statistical inference for the population parameter (parameters)
