Mathematical Statistics (I) FINAL EXAM Spring, 2011 1. Let $ X_{1}, \cdots, X_{k+1} $ be independent random variables, each having a gamma distribution with $ \beta=1 $, that is, the pdf of $ X_{i} $ is $ f_{X_{i}}\left(x_{i}\right)=\frac{1}{\Gamma\left(\alpha_{i}\right)} x_{i}^{\alpha_{i}-1} e^{-x_{i}} I\left(0<x_{i}<\infty\right) $. Let \[ Y_{i}^{\prime}=\frac{X_{i}}{X_{1}+\cdots+X_{k+1}}, i=1, \cdots, k . \] o (a) Find the joint pdf of $ Y_{1}, \cdots, Y_{k} $. (b) What is the distribution of $ Y_{1}+\cdots+Y_{r} $, where $ r \leq k $ ? $ n \cdot( $ $ x .2 .24 $ $ x $ $ x $ 2. Let $ f(x) $ and $ F(x) $ be the pdf and the cdf of a distribution of the continuous type such that $ f^{\prime}(x) $ exists for all $ x $. We say that the random variable $ Y $ has a truncated distribution, if $ Y $ has pdf $ g(y)=f(y) / F(b) I(-\infty<y<b) $. Suppose that $ E(Y)=-f(b) / F(b) $ for all real $ b $. Prove that $ f(x) $ is the pdf of standard normal distribution. 3. Let $ X $ have an exponential distribution. O (a) Show that $ P(X>x+y \mid X>x)=P(X>y) $ for any positive $ x $ and $ y $. (This property is called the memoryless property). o(b) Let $ F^{\prime} $ be the cdf of a continuous random variable $ Y $. Suppose that $ F $ has the memoryless property and that $ F(0)=0 $ and $ 0<F(y)<1 $ for $ y>0 $. Show that $ F(y)=1-e^{-\lambda y} $ for $ y>0 $ for some $ \lambda>0 $. 4. Let $ X_{n} $ converges in distribution to $ X $ and $ Y_{n} $ converges in probability to $ c $ (a constant). Show that o (a) $ X_{n}+Y_{n} $ converges in distribution to $ X+c $. (b) $ X_{n} Y_{n} $ converges in distribution to $ c X $. 5. Let $ X_{n} \sim \operatorname{Poi}(n \mu) $. (a) Find the limiting distribution of $ \frac{\sqrt{n}\left(\frac{x_{n}}{n}-\mu\right)}{\sqrt{\mu}} $. (b) Find a 'variance stabilizing transform', that is, find a transform $ h $ such that $ h\left(X_{n} / n\right) $ has asymptotic variance which is independent of $ \mu $. 6. Let $ X_{1}, \cdots, X_{n} $ be a random sample from $ N\left(\mu, \sigma^{2}\right) $ and let $ S^{2}=\frac{1}{n-1} \sum_{i=1}^{n}\left(X_{i}-\bar{X}\right)^{2} $ 6. Let $ X_{1}, \cdots, X_{n} $ be a random sample from $ N\left(\mu, \sigma^{2}\right) $ and let $ S^{2}=\frac{1}{n-1} \sum_{i=1}^{n}\left(X_{i}-\bar{X}\right)^{2} $ 1

2. (Types of Elaboration). In 2 of the universities, more females than males are more satisfied with on-campus dining options. The researcher, however, wants to dig further & use Elaboration to better understand this relationship. Which type of elaboration (i.e. spuriousness, mediation, or moderation) is needed to examine the following: a) The researcher suspects that this gender/sex difference exists only for Asian students, not Black students. b) The researcher suspects females are more satisfied because the campus always serves broccoli and it is widely known that females love broccoli & males hate it c) The researcher suspects that sex & dining hall satisfaction are not related at all. Instead, they think that the proximity of male vs. female dormitories is what matters. Most female dormitories are close to the main dining hall, which has the best food options. Male dormitories are not close to any dining hall.
