Plots (A-D) depict probability density functions, pdf ’s, for − ∞ < x < ∞ {\displaystyle -\infty <x<\infty } at the same scale. List all pdf ’s that satisfy the following criteria: ( x ¯ {\displaystyle {\bar {x}}} denotes the mean and x m e d {\displaystyle x_{med}} the median)
(i) x ¯ = x m e d {\displaystyle {\bar {x}}=x_{med}} ?
