The company's mean and median salaries would change, as the mean would increase by $5,000 and the median would not change. The correct option is (b.)

What is the mean and median?


A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When data collection is ranked from least to greatest, the median is the midpoint.

The number that appears most frequently in a data set is called the mode. In an ordered data set, the median is the value in the middle. The mean is calculated by dividing the sum of all values by the total number of values.

The changed mean = Mean + ($30000/6) = Mean + $5,000

The owner's income is the highest among all 6 employees, Hence the Median would be the same after raising $30,000 for the owner.

Therefore, the correct option is (b) The mean would increase by $5,000 and the median would not change.
