40  Difference between control group emissions and treatment group emissions
  The statistical significance (if any) of a difference between:
 (a) the mean daily emissions of greenhouse gas at sites in the treatment group in a population in the project in a measurement period in the reporting period; and
 (b) the mean daily emissions of greenhouse gas at sites in the control group in the population in the measurement period;
is worked out using the hypothesis test (hypothesis test 1):
where:
H0 means the hypothesis (the null hypothesis) that there is no difference between:
 (a) the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period; and
 (b) the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period under a counterfactual scenario.
Note: For the definition of counterfactual scenario, see section 5.
φT means the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period, in tonnes CO2‑e per day, under a counterfactual scenario.
ET means the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period, in tonnes CO2‑e per day, worked out using equation 5.
Halt means the hypothesis (the alternative hypothesis) that the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period under a counterfactual scenario is greater than the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period.
t means the test statistic for a single‑sample t‑test.
EC means the mean daily emissions of greenhouse gas at sites in the control group in the measurement period, in tonnes CO2‑e per day, worked out using equation 4.
sd means the standard deviation of mean daily emissions of greenhouse gas at sites in the control group in the measurement period, weighted by the number of days in the measurement period for which there is data, about measured energy consumption at sites in the control group, that is used for the purposes of this Part, worked out using equation 2.
fpcT means the finite population correction when using the mean daily emissions of greenhouse gas in the measurement period at sites in the control group and sites in the treatment group under a counterfactual scenario to predict the mean daily emissions of greenhouse gas at sites in the treatment group in the measurement period under a counterfactual scenario, as follows:
 (a) if the project proponent for the project chooses to use a finite population correction:

 (b) if the project proponent for the project chooses not to use a finite population correction:

NT means the number of sites included in the treatment
