Use the chart to help answer a question?? Chemistry help!!?

Here is a table that displays data from an experiment in which an air sample is subjected to different pressures:
V = volume, P = pressure

V(cm^3) P(kPa) V*P
100.0 33.3 3330
50.0 66.7 3340
25.0 133.2 3330
12.5 266.4 3330

a. Based on this set of observations, what's a hypothesis you could come up with that could be tested?

b. What theories could be stated from the data?
Sorry it looks unclear. The Volumes were: 100, 50, 25, and 12.5. The Pressures were: 33.3, 66.7, 133.2, and 266.4. And the V*P were: 3330, 3340, 3330, and 3330.
