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
