If X = lnY has a normal distribution with the mean µ and the standard deviation s, find the probability density of Y which is said to have the log– normal distribution. Use the corollary of Theorem 4.15 on page 136 to show that if X1, X2, . . . , Xn constitute a random sample from an infinite population, then cov(Xr – , ) = 0 for r = 1, 2, . . . , n. Theorem 4.15 If the random variables ...Show that, analogous to the formula of Exercise 8.17, the formula for the sample variance can be written as Also, use this formula to calculate the variance of the following sample data on the number of service calls ...Based on the result of Exercise 8.24, show that if X is a random variable having a chi– square distribution with v degrees of freedom and v is large, the distribution of X – v / √2v can be approximated with the ...Verify that if X has an F distribution with v1 and v2 degrees of freedom and v2 → ∞, the distribution of Y = v1X approaches the chi-square distribution with .1 degrees of freedom.Post your question
