Answer:
Step-by-step explanation:
The required withholding amounts are ...
- federal tax = 0.12×$1375 = $165.00
- state taxes = 0.07×$1375 = $96.25
- FICA = 0.0765×$1375 = $105.19
So, the total involuntary withholding is ...
$165.00 +96.25 +105.19 = $366.44
We want to find the voluntary withholding such that ...
(gross pay) - (involuntary withholding) - (voluntary withholding) = (net pay)
Adding (voluntary withholding - net pay) to both sides of this equation, we get ...
(gross pay) - (involuntary withholding) - (net pay) = (voluntary withholding)
Filling in the values we know gives ...
$1375 -366.44 -725 = voluntary withholding = $283.56
Your voluntary withholding is $283.56.

Answer:
Due to the higher z-score, Norma should be offered the job
Step-by-step explanation:
Z-score:
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
Whoever has the higher z-score should get the job.
Norma:
Norma got a score of 84.2; this version has a mean of 67.4 and a standard deviation of 14.
This means that 
So

Pierce:
Pierce got a score of 276.8; this version has a mean of 264 and a standard deviation of 16.
This means that 
So

Reyna:
Reyna got a score of 7.62; this version has a mean of 7.3 and a standard deviation of 0.8.
This means that 
So

Due to the higher z-score, Norma should be offered the job
