CO 27: Analyze the various data and ability to fit population distributions on data.
CO 28: Analyze the various data and ability to fit sampling distributions on data.
CO 29: Identify the problem and apply the non-parametric test and large sample test accordingly.
CO 30: Come to the conclusion with minimum data using SPRT. |

1. Plot binomial curve for different values of n and p
2. Fitting of binomial distributions when p is known and when p is unknown.
3. Fitting of Poisson distribution when λ is known and when λ is unknown.
4. Fitting of negative binomial distribution.
5. Fitting of Normal distribution
6. Calculation of areas under normal curve.
