Check the hypothesis of an exponential distribution for the item's failure and show your results numerically and graphically for the failure and reliability functions. On your plots show these functions in comparison to the ranking method results.

Check the hypothesis of a normal distribution for the item's failure and show your results numerically and graphically for the failure and reliability functions. On your plots show these functions in comparison to the ranking method results.

Check the hypothesis of a log-normal distribution for the item's failure and show your results numerically and graphically for the failure and reliability functions. On your plots show these functions in comparison to the ranking method results.

Check the hypothesis of a Weibull distribution for the item's failure and show your results numerically and graphically for the failure and reliability functions. On your plots show these functions in comparison to the ranking method results.
