Question:

The following calibration data were obtained by an instrumental method for the determination of the species X in aqueous solution:

Conc.X,CₓPPm	No. Replications N	Mean Analytical Signal, S	Standard Deviation, PPm
0.00	25	0.031	0.0079
2.00	5	0.173	0.0094
6.00	5	0.422	0.0084
10.00	5	0.702	0.0084
14.00	5	0.956	0.0085
18.00	5	1.248	0.0110

a) Calculate the Calibration sensitivity

b) Find the analytical sensitivity at each analytic concentration

c) Find the coefficient of variation for the mean of each of the replicate sets.

d) what is the detection limit for the method?
