i.e.
Sample size : n= 32
Let x be the random variable that represents the annual salary for environmental compliance specialists.
Using formula , the z-value corresponds to x= 59000 will be :
Now, by using the standard normal z-table , the probability that the mean salary of the sample is less than $59,000 :-

Lets just use 
for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being: 
. Since then new one is equal to 1, and the original is equal to 
, we see that this manipulation of the fraction causes an increase of 100%.
