Experimental data from the DoE should enable the team to compute a set of important metrics. The table below $($Main Metrics$)$ summarises the values for the rate of defective handles, the average number of defects per handle $($defects per unit $($DPU$)),$ the number of DPMO and the Sigma Level.

However, the team need your support to compute these important metrics. Please complete the table for them showing workings for calculations.
