2. It explains that inferential statistics allows generalization from a sample to a population and includes estimation of parameters and hypothesis testing.
3. Common statistical techniques covered are confidence intervals, which provide a range of values that likely contain the true population parameter, and hypothesis testing, which evaluates theories about populations.
