48 When analyzing soils for zinc content in five samples of one sample, the following results were obtained:
A) 8.5 * 10-3; 9.2*10-3
B) 10.4*10-3; 10.9*10-3
C) 7.2*10-3; 7.3*10-3
D) 9.4*10-3; 8.9*10-3
E) 7.3*10-3; 6.7*10-3
Calculate the standard deviation in determining the zinc content (for α =0.95).
