Question

The Figure below shows the calibration curve for the determination of an analyte. Knowing that the replicas of a sample showed the following signs: 0.114; 0.117 and 0.115, answer: Which option below shows the mean concentration (mg/L), standard deviation (mg/L) and relative standard deviation (%), respectively?
 

a) 144.5 mg/L; 6.7 mg/L and 1%
b) 244.5 mg/L; 3.3 mg/Le 10%
c) 227.9 mg/L; 3.1 mg/l and 1%

In the graph, the y axis represents the signal and the x axis the concentration mg/L
