For each of the following functions, (i) find the constant c so that f(x) is a pdf of a random variable X, (ii) find the cdf, F(
mel-nik [20]

Answer:

(a)

c=1/2

cdf  is    F(x) = x^2

Step-by-step explanation:

Remember that if   f  is the pdf of a random variable X .

\int\limits_{-\infty}^{\infty} f(x) \,dx = 1

Then,

(a)

\int\limits_{-\infty}^{\infty}  4xc \,dx = \int\limits_{0}^{1}  4xc \, d x = 2c = 1

Therefore

c=1/2

and

 f(x)=2x

then to compute the cdf, we have

F(x) = P(X \leq x) = \int\limits_{-\infty}^{x}   2y \,dy  =  \int\limits_{0}^{x}   2y \, dy =  x^2
