step 1. find if the differerence between the value and the mean divided by std deviation is + or -.
if it is + it falls in right tail . if it is - it falls in left tail.
step 2then find the value of z from table for eg if the value in stp 1 say +.2389. go to .23 of of z valu table and see under 8.
to step 2 add 0.5 and multiply by 100 u get %
for - subtract frm .5 valu obtnd frm step 2
