Statistics question: mean and z scores!?

Question

According to a standardised scoring system, a particular nation has a human rights score of 41 which equals a Z score of 1.3. Assuming that nations' scores have a normal distribution, what is the percentage of nations above this score?

Help much appreciated guys... please show working out too. will give you top points =)=)

Answer 1

I don't have a table of the normal distribution here.  You need one.  Look up 1.3.  If the table gives the area below that score, subtract it from 1.  If the table gives the area between that score and the mean, subtract it from 0.5.  If the table gives the area above the score, that is what you want.
