What reservoir capacity is needed so that theprobability it is exceeded is 1%? (c). What amount of water use is exceeded with 95%probablity? (d). Water is provided to approximately 1.4 millionpeople. What is the mean daily consumption per person atwhich the probablitity that the demand exceeds the currentreservoir capacity is 1%? Assume that the standard devationof demand remains the same.
