2) Examine the two-bus power system provided in the diagram. Bus 1 serves as the slack bus with a set voltage of $V_1 = 1\angle 0^\circ$ per unit (pu). Bus 2 draws a load of 100 MW and 50 Mvar. The line connecting the buses has an impedance of $z_{12} = 0.12 + j0.16$ pu, on a base of 100 MVA. (80 points) Task: Calculate the voltage magnitude and phase angle at Bus 2 using the Newton-Raphson method. Instructions: Initial Guess:** Start with an initial estimate of $|V_2|^{(0)} = 1$ pu and $\delta_2^{(0)} = 0^\circ$. Conduct two iterations of the Newton-Raphson method to refine your estimate of the voltage at Bus 2. G1 $V_1 = 1.0\angle 0^\circ$ Bus 1 Bus 2 $z_{12} = 0.12 + j0.16$ pu S=100MW+j50Mvar

Determine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions $p_1$ and $p_2$ at the level of significance $\alpha$. Assume that the samples are random and independent. Claim: $p_1 \neq p_2$, $\alpha = 0.01$ Sample Statistics: $x_1 = 32$, $n_1 = 68$, $x_2 = 33$, $n_2 = 58$ Determine whether a normal sampling distribution can be used. The samples are random and independent. A normal sampling distribution (Round to two decimal places as needed.) be used because $n_1\hat{p} = \square$, $n_1\hat{q} = \square$, $n_2\hat{p} = \square$, and $n_2\hat{q} = \square$

Question 5) Write a program that compares two arrays, A and B. Each array contains 100 8-bit signed numbers. Compare corresponding elements of the two arrays until either two elements are found to be unequal or all elements of the arrays have been compared and found to be equal. Assume the arrays start at addresses 0xA000 and 0xB000, respectively. If the two arrays are found to be unequal save the address of the first unequal element of A array in the memory location with address FOUND, otherwise write all 0s in this location. (30 points)
