56  Calculating margin of error for tree proportion
  The margin of error for the proportion of biomass killed must be calculated for each stratum using the following equation:
  Equation 22

  Where:
  the margin of error for the proportion of biomass killed in disturbed area  in stratum in reporting period
  the critical value of the t-distribution for a Student t-test, using n-1 degrees of freedom at the P=0.05 level of significance.
  the standard deviation of  the average proportion of biomass killed in disturbed area  in stratum in reporting period
  the total number of plots in disturbed area  in stratum in reporting period
