CS&F are trying to identify whether their 'bagging' process is $\text{'}$In Control' or not.

They take a sample sweet bag every half hour throughout the day and count the

number of sweets in each bag. The results have been plotted in the Control Chart

shown below.

Using the Journal of Quality Technology $($JQT$)$ rules as guidance, how many

indications of possible Special Cause Variation do there appear to be based on

the sample of data taken?

Select one:

a$.2$

b$.6$

c$.1$

d$.3$

e$.4$

f$.0$

g$.5$
