Question
a random variable whose pdf is the form of f(x)
= Cxm(1-x)
where x E (0, 1) and m is a non-negative integer.
(a) Consider the special situation of m = 1. Find the value of C such that the pdf is a proper
pdf.
(b) Argue that for a general m, the pdf must be
f (x) = (m + 1)(m + 2)x"(1 – x) for x E (0, 1).
(c) Show that the cumulative distribution function (CDF) of X is
pm+1
xm+2
F(x)
(m+1)(m + 2)
—
т +1
m + 2
(d) Continue from part (c). Evaluate the CDF at -1, 0.5, and 2 i.e., find F(-1), F(0.5), and
F(2). Be careful and think twice about your answers.
(e) In this class, we haven't studied the concept of expectation. For a continuous random
variable X, its expectation is defined as E[X] = [ xf(x)dx. Find E[X].
