Question

5 . An electrical engineer must design a circuit to deliver the maximum amount of current to a display tube to achieve sufficient image brightness Within her allowable design constraints, she has developed two candidate circuits and tests prototypes of each: The resulting data (in microamperes) are as follows: Circuit 1: 251, 255,258,257, 250,251,254,250, 248 Circuit 2: 250,253, 249, 256,259,252,260, 251 Use the Wilcoxon rank-sum test to test Ho: |l1 = Az against the alternative H : p1 > Hz. Use a = 0.025. (5 points) b. Use the normal approximation for the Wilcoxon rank-sum test. Assume that a = 0.05. Find the approximate P-value for this test statistic (5 points)
