What is the level of collaboration between nurses and resident doctors working in the intensive care unit (ICU)? This was the question of interest in an article published in the Journal of Advanced Nursing (Vol. 67, 2011). Independent samples of 31 nurses and 46 resident doctors, all working in the ICU, completed the Baggs Collaboration and Satisfaction about Care Decisions survey.

The data for the following two questions (simulated from information provided in the article) are listed above. a. Conduct a nonparametric test (at \(\alpha=05\ \alpha=05\)) to compare the response distributions for nurses and doctors on Question 4. Practically interpret the result. b.
