Problem 15E
Let the distribution of X be χ2(r).
(a) Find the point at which the pdf of X attains its maximum when r ≥ 2. This is the mode of a χ2(r) distribution.
(b) Find the points of inflection for the pdf of X when r ≥ 4.
(c) Use the results of parts (a) and (b) to sketch the pdf of X when r = 4 and when r = 10.
