Table 3.1.3 : Testing goodness of fit of gamma distribution for the observed visual defects in lots containing about 25500 Eye drop vials each Number of defects /unit Observed Frequency ( O i ) Estimated Frequency ( E i ) ( O i -E i ) 2 / E i 0.08 6 4.5404 0.4692 Totals 86 86 8.2054 p 2 = 0.0230, Prob [ χ 2 (9) > Var(p ) 2 8.205 ] = 0.513 = 0.000852 , s 2 = p . 2 2 / /Var(p ) 2 = 0.622 133
Figure 3.1.1 : Scatter plots of number of observed defects in 86 lots (each of size 25000) of eye drop. [ X axis : number of occurrences of visible particulate matters . Y axis : Number of occurrences of Leakage, breakage and Defective sealing. ] 4000 3500 Leakage+Breakage+Defective sealing 3000 2500 2000 1500 1000 500 0 0 200 400 600 800 1000 1200 1400 1600 1800 2000 Visible particulate matters Conclusion : No pattern of dependence is visible. The two types of defects may be assumed to be independently distributed. 134
