Assume that a random variable, x, is governed by the probability distribution (a version of the Lorentzian

Question:

Assume that a random variable, x, is governed by the probability (a version of the Lorentzian function)

f (x) = x2 +4'

where x ranges from ˆ’10.000 to 10.000.
(a) Find the mean value of x and its variance and standard deviation.
(b) Find the probability that x lies between Œ©xŒª ˆ’Ïƒ_x and Œ©xŒª +Ïƒ_x.
