p(92<X<108) I know p stands for probability, am I correct in assuming 92 and 108 are the range ? And what does x stand for and how do I find it ? And is there an easy step by step instruction on how do solve these with excel as the prof. wants ? I have been out of school 30 years and only had basic algebra then, Would rather you show me where each number goes. Previous info was mean=100, SD =8, and if I get a z score for 92 and 108 then p(-1<X<1) is this right so far? How do I find x and what from there? Thanks
