The standardized likelihood function of is graphically represented by a Norma l curve located by y, with standard deviation O"/y'n. 1 (a) shows a set of standardized likelihood curves which could result from an experiment in which n = 10 and 0" = l. Three different situations are illustrated with data giving averages of y = 6, Y = 9, and y = 12.
