Calculation of the confidence interval (CI):
Mean value ± s * t / sqrt(N)
s: standard deviation
t: value t-table: 4.303 (two sided, P: 95% (f = N-1))
N: number of measurements
P: probability
f: degree of freedom
Average relative density D420: 0.96145 ± 0.004049 * 4.303 / sqrt(3)
Average relative density D420: 0.961 ± 0.010 (N = 3, P: 95 %)
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
