If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean.
Z Score = (Raw Score - Mean Score) / Standard Deviation
Yes.
z = (raw score - mean)/standard error.
Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.

yes. competitive teams are scored by judges and the team with the highest score wins.
