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:

Use the Wilcoxon rank-sum test to test H_0: mu_1=mu_2 against the alternative H_1: mu_1>mu_2. Use alpha=0.025.
