This question asks us to comment on the precision and accuracy of three different targets. Precision is defined as how closely different measurements of a quantity agree with each other. Here, it will be indicated by how close together the shots on the target are grouped. Accuracy is defined as how well a measurement agrees with the expected value. Here, it will be indicated by how close the shots are to the center of the target. Target A was produced by the instructor firing a new rifle. The shots are grouped very close together, but are in the very top right of the target. This target has very high precision, as the shots are close together, but very low accuracy, as the shots are not near the center. Target B was produced by the instructor firing his personal target rifle. The shots are grouped very close together in the center of the target. This target has very high accuracy, as the bullets are at the center, and very high precision, as the bullets are grouped very close together. Target C was produced by a new student to firing. The bullets are all rather far away from the center, and they are also far away from each other. This target has low accuracy, as the bullets aren't near the center, and low precision, as the bullets aren't near each other.
