(✰✰✰✰) (a) Find the interval of values for q with the property that (for an appropriate constant K) a random variable with probability densityK₁p(x) =will have a well-defined mean but an undefined variance. Answer using interval notation, where () denotes an empty(x² + 2x+122)interval.Answer: The interval described above is {}(b) A certain random variable X has the probability density function p(x) =K2(x2+2x+122)21Find the following:K2=E[X] =Var[X] =Hint: For any random variable X and constant k, one hasE[X − k] = E[X] − kand Var[X-k] = Var[X].(Proving this is a worthwhile exercise in itself.)
