ANSWER:

Answer:

Step 1 of 3

a. The "Mean" is computed by adding all of the numbers in the data together and dividing by the number elements contained in the data set.

Mean = = 10300

The Mean for the current annual salaries is 10,300 and in terms of dollar the mean is $10,300,000.

b. The "Median" of a data set is dependant on whether the number of elements in the data set is odd or even. First reorder the data set from the smallest to the largest then if the number of elements are odd, then the Median is the element in the middle of the data set. If the number of elements are even, then the Median is the average of the two middle terms.

3500, 5000, 14000, 14500, 14500

Median = 14000

The Median for the current annual salaries is 14,000 and in terms of dollar the median is $14,000,000.
