1) Derive the following fourth order central finite difference schemes: $\left(\frac{\partial \phi}{\partial x}\right)_{i,j} \approx \frac{-\phi_{i+2,j} + 8\phi_{i+1,j} - 8\phi_{i-1,j} + \phi_{i-2,j}}{12\Delta x}$ $\left(\frac{\partial^2 \phi}{\partial x^2}\right)_{i,j} \approx \frac{-\phi_{i+2,j} + 16\phi_{i+1,j} - 30\phi_{i,j} + 16\phi_{i-1,j} - \phi_{i-2,j}}{12\Delta x^2}$

Test the claim about the difference between two population means $\mu_1$ and $\mu_2$ at the level of significance $\alpha$. Assume the samples are random and independent, and the populations are normally distributed. Claim: $\mu_1 = \mu_2$; $\alpha = 0.01$. Assume $\sigma_1^2 = \sigma_2^2$ Sample statistics: $\bar{x}_1 = 31.4$, $s_1 = 3.6$, $n_1 = 11$ and $\bar{x}_2 = 33.6$, $s_2 = 2.1$, $n_2 = 19$ Identify the null and alternative hypotheses. Choose the correct answer below. A. $H_0: \mu_1 \leq \mu_2$ $H_a: \mu_1 > \mu_2$ C. $H_0: \mu_1 < \mu_2$ $H_a: \mu_1 \geq \mu_2$ E. $H_0: \mu_1 = \mu_2$ $H_a: \mu_1 \neq \mu_2$ Find the standardized test statistic t $t = (Round to two decimal places as needed.) Find the P-value. P = (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. $H_0$. There enough evidence at the 1% level of significance to reject the claim.
