squeezing the bottle makes the pressure build up in the sealed tube pushing the water column toward the cap, the water also rises up the vertical tube. These are related by the pressure inside the squeezed container becoming greater and trying to escape somewhere, thus pushing the water column in the capped tube and pushing water up the vertical tube.

I chose the smallest reduction in the rulers because I wish to be precise with my measurements, and the largest ruler shall give me the best measurement and will allow me to read the number of tick marks to the closest measurement.

23.2 cm
I got this result by using the paper ruler and lining one end up with the end of the air column,0.0cm and the other with the cap, then read the ruler where the tube ended23.2cm.

This info portrays the amount of pressure that is built up in the bottle and is escaping through the vertical tube, it was obtained using the largest ruler and a mark at 10cm above the water line

Good data. It will serve you well in the followup experiment.
