Answer:
Both the mean and median will decrease, but the
median will decrease by more than the mean
Step-by-step explanation:
The mean is an expression giving to the average earning of the Accountants.
Average defined is total earnings divided by total Accountants hired.
When they were 4 in number and earned between $50,000 to $60,000.
One can assume the average is the mid range of this number or worked out as [($50,000 x 2) + ($60,000 x 2)] divided by 4
= 220,000 / 4 = $55,000
When the 5th Accountant was hired, because he earns very low compared to the others; the average will decline thus:
= (220,000 + $10,000) divided by 5 = $46,000
Whereas the Median would have fallen sharply from $55,000 to $35,000.
That is; ($60,000 + $10,000)/2 = $35,000
