Consider the distance traveled by a golf ball in Exercise 10-33. (a) Use the Wilcoxon rank-sum test to investigate if the means differ. Use \(\alpha=0.05\). (b) Use the normal approximation for the Wilcoxon rank-sum test with ? \(\alpha=0.05\). Find the approximate \(\text { P-value }\) for t

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 f

One of the authors travels regularly to Seattle, Washington. He uses either Delta or Alaska airline. Flight delays are sometimes unavoidable, but he would be willing to give most of his business to the airline with the best on-time arrival record. The number of minutes that his flight arrived late fo

The manufacturer of a hot tub is interested in testing two different heating elements for its product. The element that produces the maximum heat gain after 15 minutes would be preferable. The manufacturer obtains 10 samples of each heating unit and tests each one. The heat gain after 15 minutes (in

Go Tutorial Consider the chemical etch rate data in Exercise . (a) Use the Wilcoxon rank-sum test to investigate the claim that the mean etch rate is the same for both solutions. If \(\alpha=0.05\), what are your conclusions? (b) Use the normal approximation for the Wilcoxon rank-sum test. Assume tha

Consider the pipe deflection data in Exercise . (a) Use the Wilcoxon rank-sum test for the pipe deflection temperature experiment. If \(\alpha=0.05\), what are your conclusions? (b) Use the normal approximation for the Wilcoxon rank-sum test. Assume that \(\alpha=0.05\)5. Find the approximate P-value
