On the number of hurricane samples within block boundaries in which reserves are calculated
Tóm tắt
The possible (permissible) number of hurricane samples (or sections) within block boundaries is established on the basis of statistics and probability theory. The number of samples possible with hurricane-metal content is always three if the number of samples is between 20 and 500. With respect to the total number of samples, this amounts to 15.0 and 0.6 relative percent, respectively. The relative percentage of the possible samples with a hurricane-metal content decreases, consequently, with an increase in total number of samples within the block boundaries in which reserves are calculated.
