Best ResponseYou've already chosen the best response.0right now I think that we need to do 1z1z2 z1 = (ymu)/(sigma) the top y value i think is mu+1. sigma is 4. z1 = (mu+1mu)/4 = 1/4 now for y2 the bottom y value i think is mu1. sigma is 4. z2 = (mu 1mu)/4 = 1/4 so 1 1/4 + 1/4 = 1 but its not an answer, which confuses me.
