Texts: Greenberg-Seth (2004). Evaluation of a Community-Based Intervention to Promote Rear Seating for Children..pdf How did the authors and program planners develop their understanding of the problem as it occurs in the specific population and context? What was the theory/rationale used to support the program? Was it defensible? Was the program implemented as it was meant to be implemented? Explain your answer. How was the target audience's exposure to the program measured? What were the indicators? How did the researchers measure the impact/effect of the intervention? What evaluation design was used (if necessary, refer to readings and videos posted on Canvas)? What cognitive and behavioral outcomes were evaluated? What lessons learned can you draw from this intervention for future practice?

Find the Laplace transform $F(s)$ of function $f(t)$ defined by $f(t) = \begin{cases} 0, & \text{for } t < 0\\ 6t(e^{5t}\sin(2t) - \cos(2t)), & \text{for } t \ge 0 \end{cases}$ And find the final value of $f(t)$ using the final-value theorem (Hint: $\mathcal{L}(1) = \frac{1}{s}, \mathcal{L}(t) = \frac{1}{s^2}, \mathcal{L}(e^t) = \frac{1}{s-1}, \mathcal{L}(\sin(\omega t)) = \frac{\omega}{s^2 + \omega^2}$).

Question 5 Let $Y_0, Y_1,...$ be a sequence of independent, identically distributed random variable on $Z$ such that $P(Y_n = 1) = P(Y_n = -1) = 1/2$, $n = 0, 1, ...$ Consider the Stochastic process {$X_n$}$_{n \ge 0}$ given by $X_n = \frac{Y_n + Y_{n+1}}{2}$, $n = 0, 1, ...$ (5.1) Find the transition probabilities $p_{jk}(m, n) = P(X_n = k | X_m = j)$ for $m < n$ and $j, k = -1, 0, 1$. (5.2) Draw the transition probability graph for the process. (5.3) Show that the Chapman-Kolmogorov equations are not satisfied, and that consequently {$X_n$}$_{n \ge 0}$ is not a homogeneous Markov chain.
