10. Stage 1 Select a Random Sample of 3 girls Select a Random Sample of 3 boys

11. Random Sample

12. Stage 2 Carry out a suitable test to compare the two samples. We will use 15 mathematical questions.

13. Question 1 Make the largest possible three digit number.

14. Question 2 Make the smallest possible three digit number.

15. Question 3 Make the largest possible three digit even number.

16. Question 4 Make the smallest possible three digit odd number.

17. Question 5 Produce the number zero.

18. Question 6 Produce the number 3.

19. Question 7 Produce the number one.

20. Question 8 Produce a number between zero and one.

21. Question 9 Produce a number between one and two.

22. Question 10 Produce the number one without using a fraction.

23. Question 11 Produce the 13th square number.

24. Question 12 Produce the 14th square number.

25. Question 13 Produce the 31st square number.

26. Question 14 Produce the number negative three.

27. Question 15 Produce the number that is nearest to 200.

28. Stage 3 Analysis of the results Can we say that X are more intelligent than Y ?

29. Assume that males and females are equally intelligent. Then the probability that a female answers any question first is. You could then generate a tree diagram.
