4. The forward and backward finite-difference operators are defined by $D_+f(x) = \frac{f(x + h) - f(x)}{h}$, $D_-f(x) = \frac{f(x) - f(x - h)}{h}$. These operators can be applied sequentially, e.g., $D_+D_-f(x) = D_+(D_-f(x))$. 5 a) Implement the backward difference approximation $D_-f(x)$ and the central difference approximation $D_0f(x)$ to compute the derivative $f'(x)$ (defined in the class) in MATLAB. 5 b) Let $f(x) = \cos x$. Compute $D_0f$ and $D_-f$ at $x = \frac{\pi}{3}$ for $h = 0.1, 0.05, 0.025, 0.0125$. Report the errors for each $h$ by comparing against analytical solution. What is the order of accuracy for each method.

A certain math class used to have a pass rate of 85% in any given semester. After a course redesign, the course coordinator claims the pass rate is now different. Based on a simple random sample of 200 students from the redesigned math class, 155 students passed the math course. At the 10% level of significance, is there sufficient evidence to support the course coordinator's claim? Step 2 of 4: Calculate the test statistic. Round your answer to two decimal places.
