a. Have SPSS calculate Z scores for EDUC. (See the SPSS Demonstration above if this is unclear.)
b. What is the equivalent Z score for someone who has completed 18 years of education?
c. Use the Frequencies procedure to find the percentile rank for a score of 18.
d. Does the percentile rank that you found from Frequencies correspond to the Z score for a value of 18? In other words, is the distribution for years of education normal?

e. Create histograms for EDUC and the new variable ZEDUC. Explain why they have the same shape.
