Solution :
Let :
X = number of overtime hours
S = total weekly salary
S = 
S = 480 + 18X
E(S) = 

= 750
Mean of S = 750
Var (S) = 
Var(S) = 
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72

About 32.34% of the values do not lie between the z-scores of -1.3 and 0.75.
First, we need to find the region between the z-scores.
If you look at a normal distribution table, you will get the following values:
0.75 = 77.34%
-1.3 = 9.68%
Subtraction those gives us the area between the z-scores.
77.34 - 9.68 = 67.66%
Now, just subtract that value from 100% to get the amount outside of the area.
100 - 67.66 = 32.34%
