**Reiny**, Monday, January 21, 2013 at 8:28pmI assume you have either a chart for the normal distribution values, some kind of software, or you can use the internet.

Since you want 5% to lie to the right of the z score, then 95% would lie to the left of the z score.

Find .95 in the body of the table and it should be in around 1.645

My favourite is the following webpage, it replaces your old tables from your old textbooks

http://davidmlane.com/normal.html

choose button : Value from an area

In Area: enter .95

click on "below" and "recalculate"

you should see 1.645

btw, enter .05 in area, then click on "above", then "recalculate"

how about that?
