Assume that the approval rating of a Prime Minister is given by the function A(d,e), where d is defence spending (in billions) and e is education spending (in billions). The output of the approval rating A(d,e) itself is a percentage between 0 and 100. It is desirable to predict how changes to defence and education spending impact upon the PM's approval. With current spending at d0 and e0, the rate that approval (in percentage) changes with respect to defence spending (in billions) is measured by Newspoll to be the partial derivative ∂A/∂d(d0,e0) = 6.5, so an increase in defence spending of 1 billion dollars will translate to an increase in approval of 6.5%.

3. (a) Let \( X \) be a random variable having negative binomial distribution with parameters \( k \) and \( \theta \). Find the variance of \( X \). (b) Find the moment-generating function of the Poisson distribution and hence find its mean and variance. (c) If \( \mathrm{X} \) is a random variable having a binomial distribution with the parameters \( \mathrm{n} \) and \( \theta \). then the moment-generating function of

8. Consider a signal $x(n)$, given that $a = 0.81$, and is described by: $x(n) = egin{cases} a^{(|n|/2)}, & \text{n is an even integer;}\\ 0, & \text{otherwise.} \end{cases}$ (a) Sketch $x(n)$. Hint: Choose the range $|n| \le 40$. (b) Find the energy of the signal. Verify using the equation and Matlab. (c) Consider $y(n) = nx(n)$. Plot $y(n)$ and hence, determine the maximum, minimum, their corresponding values of $n$ at the max. and min. (d) Find the energy of $y(n)$.
