New Median = $

Answer 1

Answer:

a) $40920

b) $38500

Step-by-step explanation:

Given:

5 employees,

Mean = $40300

Median = $38500

Min = $32000

If he lowest paid employee gets a $3100 raise, then his salary becomes

$32000+$3100=$35100

a) If the mean was $40300, then the sum of 5 salaries is

$\ 40300\cdot 5=\ 201500$

After raising the lowest salary the sum becomes

$\ 201500+\ 3100=\ 204600$

and new mean is

$\dfrac{\ 204600}{5}=\ 40920$

b) The  lowest salary becomes $35100. It is still smaller than the median, so the new median is the same as the old one.

New median = $38500
