Hi all I am unclear about where the pivotal values are used in the calculations. For example, in the example in CT3-11 page 5, where is the pivotal value actually used in the example (besides being quoted at the beginning)? Many thanks
Do you mean the ±1.96? In which case you'll see it's the 2.5% values from the N(0,1). Perhaps this sample video from our CT3 online classroom will help: ''
