Quick question, so say I have a mean of 511, a standard deviation of 124 and then I have less then 650. I do 650-511=139. I take the 139 and divide that by 124 and get 1.12. now with the z table that would become 0.8686, how do I do the z table because i am very confused on how to convert the answer to the z table.
