Two students performed the same experiment separately and each one of them recovered two readings of mass which are given below. Correct reading of mass is 3.0 g. On the basis of given data, mark the correct optioin out of the following statements.

Options

A. Results of both the students are neither accurate nor precise
B. Results of student A are both precise and accurate
C. Results of student B are neither precise nor accurate
D. Resuls of student B are both precise and accurate

Explanation

b) Average of reading of student A`=(3.01 + 2.99)/(2) = 3.00`
B `=(3.05 + 2.95)/(2)=3.00)`
Correct reading = 3.0
Results of student A are both precise and accurate
