Statistical Signifance with Multiple Sample Groups?

Homework Statement

I will present a vary simplified version of the problem I am trying to model. Essentially I took 100 people and split them into 10 groups. To each group I tried to sell them a product. To the first group I priced the product at $5, to the second I priced it at $15, to the third $25, etc.

My null hypothesis is that the pricing of the product doesn't not influence the consumers choice to buy or not buy. My data looks something like this:

at $5 3 people bought
at $15 5 people bought
at $25 3 people bought
etc.

Again this is not my actual data, but the fundamentals are the same. What is an appropriate test I can use to show that I cannot reject the null hypothesis?

You might try a contingency table.
