As usual, the minimum of the polynomial will occur for u = Q. and the value of the minimum will be R. Show that these are the values of the mean and N times the variance as computed from the usual formulas: = E, 2 - and These values are: u= 4 and o = 5/3 u= 6 and o = 16 H = 4 and o = 106 u= 6 and o = 53/3
