Suppose that the scores of architects on a particular creativity test are normally distributed. Using a normal curve table, what percentage of architects have Z scores (a) above .10, (b) below .10, (c) above .20, (d) below .20, (e) above 1.10, (f) below 1.10, (g) above .10, and (h) below .10?

You need to know the mean and standard deviation.
Z = (scoremean)/SD 
My goof. All you need to do is find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion and its Z score.

18. Suppose that the scores of architects on a particular creativity test are normally distributed. Using a normal curve table, what percentage of architects have Z scores:
Above .10?
Below .10?
Above .20?
Below .20?
Above 1.10?
Below 1.10?
Above .10?
Below .10?
