Q45
Date Posted:

Then what about 46 and 47
Usually I post my answers on a question by question basis, because
1. Everything may not fit into a page, so splitting the questions will be better
2. If I do all at one go, it will take long for me to post answers for the questions I have completed
In some situations, I can take hours to complete one question because it is challenging or simply because I only have time to complete one question. You would not want to wait hours for a completed solution.

Q46, Q47
For Q47, the 2.5 is obtained by averaging 0 and 5, 7.5 is obtained by averaging 5 and 10 and so on. This averaging of interval values in each class is needed because we are unsure of whether more people will be in the 0 to 2.5 range or the 2.5 to 5 range and so on.
