    In this session, the June 2019 S2 Paper (Paper 72) is discussed with full explanation.

    The following concepts are discussed:

    Question 1 - Poisson distribution

                        - Poisson distribution with unknown number of trials (n)

    Question 2 - Distribution of Sample Means (X-bar)

                       - Central Limit Theorem

    Question 3 - Unbiased Estimates to Population Mean µ and Population Variance σ2

                        - Hypothesis Testing of Population Mean µ ; Lower-tail test

    Question 4 - Linear Combination of Normal Variates

                       - Normal distribution

    Question 5 - Hypothesis Testing of Population Proportion p ; Lower-tail test

                        - Type I Error in hypothesis testing and probability of making the error

                        - Confidence Interval for Population Mean µ

                        - Interpretation of Confidence Interval 

    Question 6 - Continuous Random Variables

                       - Median of a Continuous Random Variable

                       - Expectation E(X) of a Continuous Random Variable

    Question 7 - Poisson Approximation to a binomial distribution

                       - Conditions for Poisson Approximation

                       - Hypothesis Testing of Poisson Mean (λ) ; Lower-tail test
