If a rifleman's gunsight is adjusted correctly but he has shaky arms, he might shoot bullets scattered widely around the bull's-eye target. Draw a sketch of the target with the bullet holes. Does this show variation (lack of precision) or bias? b. Draw a second sketch of the target if the shots are both unbiased and precise (have little variation). The rifleman's aim is not perfect, so your sketches should show more than one bullet hole.

Explanation:

Not going to draw but I will answer it theoretically.

The shots that are consistently 2 feet left means his aim is fine but his sites are off.  It shows no lack of precision.

The second one is pretty simple aswell. every rifleman can't shoot the same hole every single shot. Many things affect it but the same technique the same time for every shot with "zero'd" sights means the rounds should be inpacting within a relativly small shot group.
