A series of tests of 19 pairs (sampling) to estimate the Time-Of-Failure (TOF, in months) yields the data given in the attached document: 'shoes'.
- Using mean-ranking method fit the data to normalpdf,log-normalpdf, andWeibullpdf
- Determine in each of the cases in (a) its mean, mode, and median.
- For eachpdf,determine the warranty period.
