Textbook Question

Chapter 7, Problem 26SE

Targets: Bias or Lack of Precision, Again

a. If a rifleman’s gunsight is adjusted correctly, but he has shaky arms, the bullets might be 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 unbiased and have precision (little variation).

The rifleman’s aim is not perfect, so your sketches should show more than one bullet hole.
