Answer:
4 %; 3 %; 9.6 %
Explanation:
[tex]\text{Percent deviation} = \dfrac{\lvert \text{Measured - Actual}\lvert}{ \text{Actual}} \times100 \,\%[/tex]
Student 1
[tex]\text{\% deviation} = \dfrac{\lvert 140 - 146\lvert}{146} \times 100 \, \% \\\\= \dfrac{\lvert -6\lvert}{146} \times 100 \, \% = \dfrac{6}{146} \times 100 \,\% \\\\= 0.04 \times 100 \, \% = \textbf{4 \%}[/tex]
Student 2
[tex]\text{\% deviation} = \dfrac{\lvert 150 - 146\lvert}{146} \times 100 \, \% \\\\= \dfrac{\lvert 4\lvert}{146} \times 100 \, \% = \dfrac{4}{146} \times 100 \,\% \\\\= 0.03 \times 100 \, \% = \textbf{3 \%}[/tex]
Student 3
[tex]\text{\% deviation} = \dfrac{\lvert 160 - 146\lvert}{146} \times 100 \, \% \\\\= \dfrac{\lvert 14\lvert}{146} \times 100 \, \% = \dfrac{14}{146} \times 100 \,\% \\\\= 0.096 \times 100 \, \% = \textbf{9.6 \%}[/tex]
