Question

Can any of the following values be rejected at the 95% confidence interval using the Grubbs test?

0.8452             0.8265             0.8401             0.8422             0.8397

Average = 0.83874

St. Dev. = 0.007181


1)Yes, 0.8265 should be eliminated because Gcalc is 1.71 and Gcalc > Gtable.
2)No, data can never be eliminated using the Grubbs test.
3)Yes, 0.8265 should be eliminated because Gcalc is 1.71 and Gcalc < Gtable.
4)Yes, 0.8452 should be eliminated because Gcalc is 0.90 and Gcalc < Gtable.
5)No, 0.8265 should not be eliminated because Gcalc is 1.71 and Gcalc < Gtable.
6) Yes, 0.8265 should be eliminated because is it 0.0132 away from the next nearest value.
