ii$.$ What flow is exceeded $2\%$ of the time? $[2]$

iii. What flow is exceeded $95\%$ of the time?$[2]$

iv$.$ What is the average flow of the river during the time period? $[2]$

v$.$ Estimate the volume of flow in a one $-$ year time period $[4]$

vi$.$ If at least $50$ cumecs of flow is needed to generate a minimum power demand how

many days in a year will the power station fail to meet the demand? $[4]$
