Question 35. Let X be a random variable defined by the density function aßa if x > B f(x) = xa+1 , else with parameters a > 0 and ß > 0. We observe a sample {3,4,8}. Which of the following statements are correct? a) The expected value of X exists for all combinations of a and B. b) The expected value does only depend on a, but not on B. c) Given the sample, B can not be larger than 3. d) If we assume B = 2, the estimation of the expected value from the sample mean leads to an estimate of for 3 a. e) is also the maximum likelihood estimate of a in this case. 3
