How do you the area of the normal curve between two numbers,
i.e. P(a<Z<b)?
There is an easy sequence of commands to do this:
- [2nd] [vars] "normalcdf"
- a,b [enter]
If you want the area between two numbers, and it is not the standard
normal, ie mean=m, standard deviation=s, then
- [2nd] [vars] "normalcdf"
- a,b,m,s [enter]
