In my experiment I ended up surveying 15 people, 10 female and 5 male. As I was organizing the information I collected from my experiment I made 3 age groups which I made into charts (as seen below). I divided them into 3 age groups  13-25, 26-50, and 51+. There were 9 in the 1st group, 4 in the 2nd group and 2 in the 3rd group.

As you can see from the charts smell does affect taste. You can also conclude that you could taste the flavor more when you were plugging your nose instead of smelling the peppermint.
