A cylinder and an airtight piston are used in the following experiment. The piston is pushed up and down in the cylinder and the resulting pressure of the air inside the cylinder is measured with a pressure gauge. The results of the experiment are recorded in the following table: Volume of Air (L) Pressure Reading (Atm) 8 1 4 2 2 4 1 8 A hypothesis concerning the apparatus is stated as follows: "When the volume of the cylinder is decreased, the pressure is increased." Which of the following statements is true?
A. The hypothesis is supported by the experimental data.
B. The hypothesis is refuted by the experimental data.
C. The hypothesis is not addressed by the experiment.
D. There is not enough information to make a judgment about the hypothesis.

Graph that

Every time you cut the volume in half you double the pressure
P V = k = 8
so
P = 8/V
so yes, confirmed
