(i) Results of both the students are neither accurate nor precise.
(ii) Results of student A are both precise and accurate.
(iii) Results of student B are neither precise nor accurate.
(iv) Results of student B are both precise and accurate.

Answers (1)

The answer is the option (ii) Results of student A are both precise and accurate.

Explanation: First, we calculate, the average of both the readings of student A and B. Student A's average is 3.00, and student B's average is also 3.00. The correct reading of the mass is 3.00g. Therefore, both the students have gotten an average value close to the correct value and are accurate. But student A's values differ only by 0.02 and are precise while B's readings are not close to each other and differ by 0.1, and thus are not precise.

Therefore, A has the readings which are both precise and accurate.
