Describe a 5-step hypothesis test using any one of the nonparametric tests in your reading  material for a particular claim related to your work or life environment.  You need to state the  claim, define the null and alternate hypotheses, identify the test significance and the test statistic,  and state the decision rule that will be used.  The decision rule may be based on critical values or  on   the   p-value   approach.  You   do   not   need   to   collect   data   and   actually   conduct   the   test  calculations unless you wish to do so. Here is an example of a nonparametric hypothesis test: A study regarding the relationship between age and the amount of pressure sales personnel  feel   in   relation   to   their   jobs   revealed   the   following   sample   information.   At   the   .01

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
