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 = (score-mean)/SD
Z = (score-mean)/SD
