Final answer:

Jeff has demonstrated poor accuracy and good precision in his shooting at the rifle range as his shots were clustered together but away from the bullseye.

Explanation:

When Jeff shoots at a rifle range and notices that his 20 bullets are clustered in one small area on the lower right hand corner of the paper target, he is demonstrating poor accuracy and good precision. Accuracy refers to how close the shots (or measurements) are to the intended target, which in this case would be the bullseye. Since Jeff's shots are away from the bullseye, his accuracy is poor. Precision, on the other hand, refers to the closeness of the shots to one another. As Jeff’s shots are closely clustered together, even though they are not near the bullseye, his precision is considered good. This example is similar to throwing darts at a dartboard where all the darts land in a tight group, but not near the bullseye, representing precise but not accurate.
