Problem 2: (30 points) Statisticians are modeling measurement errors X of a specific physical quantity which follows the following probability density function (pdf). f(x) = x2,-1 Sx si elsewhere (a) Show that f(x) a valid density function. (b) Find the probability that a random error in measurement is less than 1/2. -**-
(e) Determine the mean of x. (d) Determine the variance of X. (e) Find cumulative distribution function of the pdf.
