The May 2014
Section A – both questions are compulsory Section B – consists of eleven (11) questions of which eight (8) must be answered. Areas where students did not perform well in the previous examination session are the following: 1. Choose the correct formula to answer a question – ensure that you are familiar with all the formulas, and their specific uses. Also make sure that you know when to use the formulas for grouped vs. ungrouped data. 2. When doing hypothesis testing questions, remember to include everything you are asked for, i.e. null AND alternative hypotheses, rejection areas, AND a conclusion with your rejection statement. 3. Don’t ‘abandon’ questions midway – show all working out, show all elements of the formula, and always end off with a conclusion or recommendation. Marks are easily lost by not giving a complete calculation. 4. READ THE QUESTION CAREFULLY!
For the upcoming examination session it is important that students have a good understanding of the following concepts:
