Determine the area under the normal curve between Z 113 and
Determine the area under the normal curve between Z = -1.13 and Z = .67
Solution
z1 = lower z score =    -1.13      
 z2 = upper z score =     0.67      
           
 Using table/technology, the left tailed areas between these z scores is          
           
 P(z < z1) =    0.129238112      
 P(z < z2) =    0.748571105      
           
 Thus, the area between them, by subtracting these areas, is          
           
 P(z1 < z < z2) =    0.619332993   [ANSWER]
