Normal Distribution

[summertigger]

In a normal distribution with u=200 and o=30 find the percentage of values that are between 180 and 195.

If I could get an example of this that would be great Thanks!

Did I do this right?
z=(180-200)/30= -.67
= .2486

Z=(195-200)/30= -.17
=.0675

=.2486-.0675
=.1811

=18%
