(Answered) Targets bias or lack of precisiona if a riflemans gunsight

Statistics

Targets: Bias or Lack of Precision?

a. 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 bullet hole.
