Question

If a​ rifleman's gunsight is adjusted​ incorrectly, he might shoot bullets consistently close to 2 feet left of the​ bull's-eye target. draw a sketch of the target with the bullet holes. does this show 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 bullethole.

Answer 1

Not going to draw it since i'm horrible at drawing but it's pretty simple. 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.
