Completely randomized experiment and observational study.

The makers of Frumpies, "the breakfast of rug rats," want to improve their marketing, so they consult you:

a) They first want to know what fraction of children, ages 10 to 13, likes their celery-flavoured cereal. What type of study should they perform?

b) They are thinking of introducing a new flavour, maple-marshmallow Frumpies, and want to know whether children will prefer the new flavour to the old one. Design a completely randomized experiment to investigate this question.

c) They suspect that children who regularly watch Saturday morning cartoon show starring Frump, the flying teenage warrior rabbit who eats Frumpies in every episode, may respond differently to the new flavour. How would you take that into account in the design?
