Question

The customers at a local appliance store are polled as they leave the store. Each is asked, “What brand of appliance do you prefer?” The random variable x to be reported is whether the appliance brand is Frigidaire. Is x a binomial variable? Justify your answer.

Answer 1

Well, it is a binomial variable as long as you limit the amount of people you ask to a certain number for every trial.
Also, you MUST record the data either as they choose Frigidaire or they didn't choose Frigidaire. It MUST be these two choices, or it isn't binomial.
