Hi all, A problem is that in the formulae and tables, the standard normal probabilities only contains x has two decimals, but usually in the question it needs four decimals. How do you handle it? By using the calculator? Thanks a lot. Minze
Just linearly interpolate between the values given in the tables. eg. phi(1.00) = 0.84134 phi(1.01) = 0.84375 phi(1.0125) = 0.25*(phi(1.01) - phi (1.00)) + phi(1.00) = 0.84194.
Thank you very much It works. Just more time to work, I am afraid of short of time during examination.
The key for the CT exams is to practice questions in topics - this is the most efficient way to learn and improve your speed.
