Can someone please solve this before April 17th at 11 pm (EST)
Suppose X has a binomial distribution with parameters n ≥ 1 and p ∈ (0, 1) (i.e., X ∼ Bin(n, p)). Compute E(X) and Var(X) by using the mgf.

Having troubles with question 2. Please help
2. If X has a Gamma distribution with parameters a and B, then its mgf is given by (a) Obtain expressions for the moment-genérating functions of an exponential random variable and of a chi-square random variable by recognizing that these are special cases of a Gamma distribution and using the mgf given above. (b) Suppose that X1 is a Gamma variable with parameters α1 and β, X2 is a Gamma variable with parameters...
4) Suppose a random variable X has theprobability distribution with a: o 1 -2 0 1 2 0.3 0.1 p 0.4 . then p - ,P(X2 22) = ,, and E(X) = - 5) Suppose X~Bin(10,0.4), Y-2X+5, then E(Y) = ,Var(Y) 6) Suppose X-NC-3,4) and Y~N(2,9), X and Y are independent, then Var(X-2Y)

The probability mass function (pmf) for the Poisson distribution can be regarded as a limiting form of the binomial pmf if n o and p 0 with np = fi constant. (a) Suppose that 1% of all transistors produced by a certain company are defective. 100 of these chips are selected from the assembly line, Calculate the probability that exactly three of the chips are defective using both a binomial distribution and a Poisson distribution....

Suppose that X (X1,X2, . . . , X.) ald Y-(Yİ,%, , Y,n) are random samples from continuous distributions F and G, respectively. Wilcoxon's two-sample test statistioc W- W(X,Y) is defined to be X/Ri where Ri is the rank of Y in the combined sample. 1. Let T Z, where Z, Z2,, Zm are numbers sampled at random without replacement from the set {1,2,...,N) Show that E(Z) = (N + 1)/2 and...
Please solve on only PART 2 b)
and c) , PART 1 is only for REFERENCE :)
Part I: Ene concept of a percentile (equivalently, quantile) is very important in data analysis. It applies to both samples and distributions. So, let's get some wi practice with them, starting with the binomial distribution. In prelab, you learned that the function gbinom(p. size prob) gives the p-th quantile of the binomial distribution with parameters n - size and pi prob. tocus on...
