The following table that depicts the number of accidents associated with Systems A and B:

Develop the cumulative frequency distributions for A and B. Plot these distributions. What qualitative conclusions can you make based on the plots? Would you be willing to extrapolate the number of accidents for these two systems to year 2005. Give a simple idea of how you would characterize the uncertainty in the extrapolation. How would you characterize the variability about your forecast to the year 2005?
