The answer is b. In a table that is provided
Assuming the costs are normally distributed, then Z = (X-mu)/sigma
For piano Z= (3000-4000)/2500 = -0.4
For guitar Z= (550-500)/200 = 0.25
For drums set Z= (600-700)/100 = -1
Drums set < Piano < Guitar
Drums cost is lowest when compared to the instruments of same type
.
Guitar cost is highest when compared to the instruments of same type.
Answer:
B) $77,350
Explanation:
Gross payroll=$100,000
Social Security taxes =6.20%
6.20/100×$100,000
=0.062×$100,000
=$6,200
Medicare taxes = 1.45%.
1.45/100×$100,000
=0.145×$100,000
=$1,450
federal and state income tax =15%
15/100×$100,000
=0.15×$100,000
=$15,000
Total Withholdings=
$6,200+$1,450+$15,000
=$22,650
Total employee compensation= Gross earnings-total withhold
=$100,000-$22,650
=$77,350
