Hi! I had this one last question on my homework that I wasn't sure about, but, I need someone to check this for me and see if this is right. Thanks so much!

Question: The study that looked at prevalence of various appliance in homes in 2001 made a comparison to the percentages for each appliance in 1987. For example, microwave ovens to 96% in 2001. Answering machines were in 10% of the homes in 1987 as opposed to 78% in 2001.

Responses:

a.) There are two variables involved; what is the explanatory variable? Not here, which year (1987 or 2001), percentages, or appliances?

My answer: Percentages

c.) What is the response variables? Years or what percentage of the homes had appliances?
