Solution

z1 = lower z score =    -1.18      
z2 = upper z score =     2.47      
          
Using table/technology, the left tailed areas between these z scores is          
          
P(z < z1) =    0.119000107      
P(z < z2) =    0.993244347      
          
Thus, the area between them, by subtracting these areas, is          
          
P(z1 < z < z2) =    0.87424424 [ANSWER]

So, if your z scores are correct, then your answer must be correct.

Are you sure the z scores are -1.18 and 2.47? If so, please report this problem to your instructor.
