Statistic and Probability project

projectpart2.docx

The data comes from following website, I random select 150 observations, x variable is Age.

Mean :37

Variance: 361

Standard deviation: 19

4) Suggest an appropriate probability distribution to approximate the histogram. I suggest exponential distribution

6) Give reasons why your selection of probability distribution is appropriate.

I would select exponential distribution because it is positively skewed and probabilities decreases as we move forward

Part two

Use the procedure followed in Gretzky's example to approximate the distribution by a probability density curve.（see attachment, shark attacks）

7) Perform Goodness of fit test of the distribution

8) Find the pdf, cdf, empirical cdf, mgf, expected value and variance.

9) Give conclusions of the results obtained.

10) Discuss any limitations of your study.

11) Discuss your perception about the project before and after completion.
