An instructor at UD wants to conduct a  survey from students of Math 114 to know the opinion of students about online learning. He wants to have a sample size of 50. Some sampling techniques are described here below. Match the techniques with the appropriate methods.  A.  Assign each student in Math 114 a number. Select a student randomly and then pick every 5th students from the sequence until the expected sample size is reached.  B.   Divide the students according to their major: Nutrition and Dietetics, International Relations, Criminal Justice, Psychology, University Studies, political Sciences, medical Diagnostic, Criminal Justices, Economics, and Others. Then pick 3 majors randomly and include all the students from those selected majors. C.  Ask 5  Math 114-instructors to interview 10 students who are approachable to them in their sections.  D.  Assign each student in Math 114 a number. Then use a random-number table to select 50 students for the sample.  E.  Divide the students into 10 sections (for instance, section 010, 011, 012 etc.) and then take  5 students from each section.
