Suppose that the scores of architects on a particular creativity test are normally distributed. 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, (h) below -.10?
(a) From the normal curve table - 3.98% (.398) have Z scores between the mean and .10. By definition a total of 50% have Z scores above the mean. Thus 50% minus 3.98% have Z scores ...
