a) $82,754.00
b) $89,953.00
c) $90,567.00
d) $92,635.00

Answer 1

To find the mean of a data set, add up all the values and divide by the number of values. In this case, the mean is $91,260.00. Option c) $90,567.00 is the closest answer choice.

Step-by-step explanation:

To find the mean of a data set, we add up all the values in the data set and divide the sum by the number of values in the data set. In this case, the data set consists of the following salaries: $86,390.00 $109,280.00 $91,460.00 $87,120.00 $88,390.00 $93,360.00 $95,470.00 $89,610.00.

Step 1: Add up all the salaries: $86,390.00 + $109,280.00 + $91,460.00 + $87,120.00 + $88,390.00 + $93,360.00 + $95,470.00 + $89,610.00 = $730,080.00.

Step 2: Divide the sum by the number of salaries (which is 8 in this case): $730,080.00 ÷ 8 = $91,260.00.

Therefore, the mean of the data set is $91,260.00. Option c) $90,567.00 is the closest answer choice.
