Question 13
Statement A student proposed a hypothesis that fewer students are born in the first half of the year than the second half of the year. She wrote the following procedure which uses the “Scores” dataset to verify the hypothesis. However, the procedure may contain some errors. Find out the errors if present. Step 1: Arrange all cards in a single pile called Pile 1 Step 2: Maintain two variables A and B and initialize them to 0 Step 3: If Pile 1 is empty then stop the iteration and start from Step 8 Step 4: Read the top card in Pile 1 Step 5: If the Date of Birth is from 1st January to 30th June then increment A Step 6: If the Date of Birth is from 1st July to 31st December then increment B Step 7: Move the current card to another pile called Pile 2 and repeat from Step 3 Step 8: If A > B then declare the hypothesis to be True Step 9: If A ≤ B then declare the hypothesis to be False
Step 5 to increment A is incorrect
Step 6 to increment B is incorrect
Step 8 to declare the hypothesis as True is incorrect
Step 9 to declare the hypothesis as False is incorrect
The procedure is free of errors
