- does anyone know why sometimes the p value is taken away from 1, other times you minus it from .5 and other times its just left?
- and does anyone know how to get a value of a confidence interval?
thanks and sorry i know they're quite easy!!
we're doing it in 2nd year calculus in university?? is it not??
by confidence interval i ment find confidence interval of say 95.66 i know theres a table for 95 90 but other than them figures how can you find the confidence interval.
and p value when you are doing hypothesis testing how do you know how to get the p value. and using z test for both
sorry i wasn't clear enough
