It is evident from Figure1.5 that the proportion of defects is the sum of
the area on the left side of 19 and the area on the right side of 31. Using
Minitab
®
, the area on the left side of 19 can be calculated as 0.0000034 (see
Figure1.6).
Similarly, Minitab
®
can be used to calculate the area on the left side of 31
as shown in Figure1.7. Notice in Figure1.7 that the area on the left side of
31 is 0.999767. This means that the area on the right side of 31 is 0.000233 (i.e.,
1 – 0.999767). Hence, the proportion of defectives
= Area on the left side of 19 + Area on the right side of 31
= 0.0000034 + 0 ...
