88  Calculating uncertainty for net abatement amount
 (1) Uncertainty for the net abatement amount for a project must be calculated as a 90% confidence interval in accordance with this section.
 (2) The size of the 90% confidence interval for the net abatement amount for a project is to be calculated for the reporting period using the following formula:
  Equation 1c

  where:
       =  half the width of the 90% confidence interval for net abatement amount for a project for the reporting period in tonnes of CO2‑e (t CO2‑e).

       =  standard error for net abatement amount for a project for the reporting period in tonnes of CO2‑e (t CO2‑e), calculated in accordance with Equation 1d.

       =  two‑sided students t‑value for the 90% confidence level at the appropriate degrees of freedom ( ‑1), where n is the number of plots in stratum  assessed during the reporting period, calculated in accordance with Equation 1e.
