Hermit crabs fight for ownership of shells.  Fights are initiated when one crab raps on the shell of another with its big claw.  An exchange of shells occurs approximately 50% of the time.   Investigators wish to see if the rapping force helps decide the issue.  They set up an experiment with a rubberized shell, which would dampen the force of the rapping.   They reason that the reduced force should result in fewer exchanges of shells.   They then observed 59 fights to see how many shell exchanges occurred.

What null and alternative hypotheses should the investigators use?
