Problem 1 – The employees have indicated that 95% of employees in one of the departments are receiving higher salaries than any other department because their supervisor parties with them each weekend. Some employees only have an hourly rate which you have to calculate their yearly salary before completing the calculations. Please calculate the 95% standard deviation for each department and indicate for me if any department is receiving on average $2K or more on the high end.

Dept 1 Dept 2 Dept 3 Dept 4 Dept 5

$22,450 18,550 B 22555 19050

$30,050 27,050 16765 29950 21545

$23,785 26,785 30050 23785 27950

A 25050 29955 B 27550

$27,594 26557 A 27650 25550

A-$9/hr @ 40 hrs week @50 weeks a year

B-$11/hr @ 35 hrs week @52 weeks a year

Is any department receiving on average $2K or more on the high end of the standard deviation using standard deviation at 95%? If so, which department and be sure to explain your answer.
