43  Calculating margin of error for stocking density
          (1) The margin of error for the average stocking density of a CEA must be calculated using the following formula:
  Equation 3

          where:
  margin of error for the average stocking density (in stems/ha) for the ith carbon estimation area.
  critical value of the t-distribution for a student's t-test, using Mi -1 degrees of freedom at the P=0.05 level of significance.
  standard deviation of average stocking density (z̄) for plots within the ith carbon estimation area.
  total number of plots in the ith carbon estimation area.
  ith carbon estimation area.

          (2) The standard deviation of the average stocking density for plots within the CEA must be calculated using the formula for sample standard deviation using Equation 4 as follows:
   Equation 4

          where:
  standard deviation of average stocking density (z̄) for plots within the ith carbon estimation area.
  average of the stocking density zi j for j plots within the ith carbon estimation area.
  stocking density (in stems/ha) of the jth plot in the ithcarbon estimation area.
  total number of plots in the ith carbon estimation area.
  ith carbon estimation area.
  jth plot.
