sampling/probability/correlation?

#1
I have in my course this problem
do you have any idea from people who work daily with stats ?

the question is like that:
the following data are available concerning the products of a firm taken at random from four factories, and classified according to level of quality:

Factory A : from low to good : 9 - 22 - 69 total 100
factory B : from low to good: 12 - 52 - 136 total 200
Factory C : from low to good : 6 - 30 - 64 total 100
Factory D : from low to good: 3 - 16 - 81 total 100

Is there any evidence to suggest that the level of quality is significantly associated with particular factories ?

evidence ??


for me I will say that there is a correlation between qtty produce more we do more we tend to a curb but beside that nothing
