Verify the expression given for µ'2 in the proof of Theorem 6.5.
Answer to relevant QuestionsShow that the parameters of the beta distribution can be expressed as follows in terms of the mean and the variance of this distribution: (a) (b) Show that the differential equation of Exercise 6.30 with b = c = 0 and σ > 0 yields a normal distribution. In exercise With reference to Exercise 6.39, show that for nor–mal distributions k2= σ2 and all other cumulants are zero. In exercise If we let KX(t) = lnMX – µ(t), the coefficient of tr/r! in the Maclaurin’s series of KX(t) is ...Use the results of Exercise 6.4 to find α3 and α4 for the uniform density with the parameters α and β. If the annual proportion of erroneous income tax returns filed with the IRS can be looked upon as a random variable having a beta distribution with α = 2 and β = 9, what is the probability that in any given year there will ...
