, where 
is the standard deviation and 'n' is the sample size.
Given: Mean : 
Standard deviation : 
Sample size : 
Now, the value of the standard error of the average annual salary is given by :-
Hence, the standard error of the average annual salary = 478
Aidan used
170 * 0.37 = $62.90
it costed:
60 * 0.37 = $22.20
hence change in expense will be:
