Extracted text: Requirements: 1. State what non- parametric tests to use in the following problems 2. Give the null and alternative hypothesis in a sentence format or words a. A sample of 10 students were given a diagnostic test before studying a particular module and then again after completing the module. We want to find out if, in general, teaching leads to improvements in students' knowledge/skills. We can use the results from our sample of students to draw conclusions about the impact of this module in general. Student no.
