A couple of days ago I received response to a questionnaire I've mailed to 6 categories of people.

Not all people in each category answered the questionnaire, and now I would like to know if one group responded significantly less, than the other groups.

The answers in percent for each group is:

65 %

55 %

50 %

50 %

40 %

30 %

Is it possible to do some statistical calculations on this?

I really hope that you can help me.
