It is appropriate when there is credible data source and policy makers need to be convinced on an investment that is worthwhile. Also, change can happen anytime and planners must be able to set an argument that greater change will most likely occur by chance alone. The Z-test is used to determine the amount of change that is statistically significant. Very often, the significance level is set at p= 0.05 which implies that the probability of reaching the target by chance alone is 5% or less than 5 in 100 which translates to a Z-score of 1.96 which is used to estimate the target value.
