The chi-squared distribution with parameter $n > 0$ is denoted as $\chi_n^2$. If $X \sim \chi_n^2$, then X has probability density function (pdf) $$f_X(x) = \begin{cases} \frac{1}{2^{n/2}\Gamma(\frac{n}{2})} x^{\frac{n}{2}-1} e^{-\frac{x}{2}}, & x > 0, \ 0, & \text{otherwise.} \end{cases}$$ a. Show that the k-th raw moment $$E(X^k) = 2^k \frac{\Gamma(k + \frac{n}{2})}{\Gamma(\frac{n}{2})}, \quad k = 1, 2, \dots$$ b. Hence, show that the mean, variance, skewness and kurtosis of the $\chi_n^2$ distribution are $$E(X) = n,$$ $$Var(X) = 2n,$$ $$\zeta_3 = \sqrt{8/n},$$ $$\zeta_4 = 3 + \frac{12}{n}$$ c. Judging from $\zeta_3$ and $\zeta_4$, what would you say happens to the shape of the $\chi_n^2$ pdf for large n?

Page 5 21. Looking closer at the different types of fuels used today on Earth for providing energy, what are the benefits and risks involved in using these fuels. What fuels do you think we will be using 100 years from now (to provide energy)? State why and what safeguards we need to use. Discussion should be at least a page long and include pertinent information about how to sustain each fuel type, how long it lasts, whether it is reusable, renewable, or not, and, where it is more appropriate to use that type.
