   Question

   A researcher wants to compare two independent groups (full-time students and part-time students) on the distribution of their scores on a practicum. He considers the scores to be measured at the ordinal measurement level. The null hypothesis is that the two distributions are the same.

   Group 1: 2, 3, 4, 4, 6 Group 2: 5, 6, 7, 8, 9

   If two-sided testing is done at 5% then:

   
   
   1. TRUE: H0 must be rejected because Uobt < Ucrit
   2. FALSE: H0 must be rejected because Uobt > Ucrit
   3. FALSE: H0 should not be rejected because Uobt < Ucrit
   4. FALSE: H0 should not be rejected because Uobt > Ucrit
