Given the two independent samples below, conduct a hypothesis test for the desired scenario. Assume all populations are approximately normally distributed. Sample 1 Sample 2 n1= 882 n2= 807 x¯1= 399 x¯2= 429 s1= 157 s2= 165 Test the claim: Given the null and alternative hypotheses below, conduct a hypothesis test for α=0.01. H0: μ1=μ2 Ha: μ1<μ2 Given the alternative hypothesis, the test is Select an answer left-tailed right-tailed two-tailed Determine the test statistic. Round to four decimal places. t= Find the p-value. Round to 4 decimals. p-value = Make a decision. Reject the null hypothesis. Fail to reject the null hypothesis.

2) A register is a group of flip-flops of some given width used to hold data or code. A shift register arranges the register so the data moves left or right on the system clock edge. A Johnson counter, like the one shown here, is arranged to recirculate the register contents so a fixed sequence of codes is generated. There may be logic between each flip-flop to make the sequence more convoluted. Compute the list of codes generated by this circuit for every present state (PS) code.

3. The region $z > 0$ of space is occupied with a dielectric material of permittivity $\varepsilon = 2\varepsilon_0$, while the region $z < 0$ is free space. The electric field in the region $z < 0$ is given as $\vec{E} = 5\hat{a}_x + 2\hat{a}_y - 3\hat{a}_z$ V/m. Find the electric field in the region $z > 0$.
