In this test, the T-test used the following criteria for determining signifcance: If p<0.05, the differ- ence between an EJ community and a Non-EJ community is signifcant or likely to occur; If p>=0.05, the difference between an EJ commu- nity and a Non-EJ community is insignifcant or unlikely to occur. 168 North South Rail Link Feasibility Reassessment Final Report January 2019 | Appendices B. Full List of Upstream Improvements “Critical” interventions must be in place for a particular service plan to be implemented. “Recommended” interventions reduce performance risks for a particular service plan and its associated level of service.
