For Guru Week Two: (See the detail Figures in Article published on 27 Jan) Mean of % Drop: .53% Confidence Level (95%)=.13% It means with this sample and data, I am 95% confident that mean of % drop will falls between (.53+.13) and ((.53-.13). Upper Limit of Drop =.66% Lower limit of Drop =.40% So Total Expected(Considering BOI): For Upper Limit=5.98 Cr For Lower Limit=10.74 Cr So Total Expected(Considering IBOS): For Upper Limit=6.94Cr For Lower Limit=12.4Cr These both values are much more comparable to actual figures put forward by these sites.
