A community hospital system realized that approximately 2,000 patients were leaving its emergency department (ED) each year without receiving medical attention. This hospital system realized that majority of these patients who did not receive medical attention had minor ailments and conditions which could be treated by a primary care physician. However, the patients who were leaving without medical treatment was negatively affecting the ratings of the hospital system so they hired you as a Public Health Administrator to help improve service delivery at the ED. In your first month in as the Administrator, you realized that 500 patients left the ED without receiving medical attention, which was higher than the 200 reported for the same month last year. To help understand why these patients were leaving without receiving medical care, you reach out to a few of them. You then realized that the main issue that these patients who did not receive care and other patient who even received care complained about the was the rudeness and unprofessionalism of the staff at this hospital. From the perspective of the staff, majority of them attributed the issue to overcrowding in the emergency department. Knowing that overcrowding can definitely influence how staff worked at the ED, you implemented a mandatory training program in good customer service practices for all the 50 staff working at the ED in your third month of employment. You made all staff complete a Customer Relationship Management (CRM) Questionnaire before and after the mandatory training program. The scores range from 0 (poor customer relation) to 100% (excellent customer relation). Participants who only English were selected to participate in a sub-study.Perform non- parametric tests on the following situation.

a. What kind of test should you perform to evaluate if the training program brought about a change in customer relation scores comparing the scores before the training program and the scores after the customer relation training program? Support your answer with statements (ideally a short paragraph)

b. In the main study which had 50 participants, the proportion of men was 46%. What type of test should you perform a test to confirm if the proportion of men in the sub-study is consistent with this statistic?
