Question

1. Discrete distribution for X' is given by the following table: Probabilities p Values A 0.2 20 0.2 40 0.3 60 0.2 80 0.1 100 Find distribution function fax) and median Me(X). Calculate expectation value MX), variance (dispersion) DA), standard error σ(X), asymmetry coefficient As(X) and excess Ex(X). 2. Calculate multiplier k. Find distribution function foc), mode Moc), median Me(x), expectation value M(x), variance (dispersion) D(x), standard error σ(x), asymmetry coefficient As(x) and excess Ex(x) for continuous distributions with the given probability densities a) b) 0 r<-2 -2 r>6 0sxs8 ρ(x) = k(4x-x2 +12) 6 x 1r+1 8s10 10 x>10 Calculate probability that X E 1-28 Calculate probability that x e -3:2]

This is a statistics question, unfortunately I have difficulties understanding problems with statistics and I need this question solved with full workings and also in an understandable way to revise. Your help will be highly appreciated, *I will give positive rating to the fullest*. Thank you!!
