In same year question 3, for 90% confidence level how has the examiner got 1.282 won’t it be 1.289 as we are looking for .40.
ThanksPlease – you must ask in the Ask the Tutor Forum if you want me to answer!
I cannot say that it is a rule, but the current examiner does always set out the question well and in a helpful way.
We are looking for 0.40, and the nearest in the table is 1.28 (giving 0.3997). I would leave it at 1.28, but the examiner as apportion between 1.28 and 1.29. We need an extra 0.0003, the difference between 0.3997 and 0.4015 is 0.0018. So he has got 1.28 + (3/18) = 1.282.
