Question 480972
Math test has a mean of 41 and standard deviation of 5.0. Find the corresponding z scores for: 

I. a test score of 18
z(18) = (18-41)/5 = -23/5 = -4.6
========================================
 
II. a test score of 55
z(55) = (55-41)/5 = 14/5 = 2.8
==================================
