5) The mean salary of 5 employees is $40300. The median is $38500. The lowest paid employee's salary is $32000. If the lowest paid employee gets a $3100 raise, then ...


a) What is the new mean?

New Mean = $



b) What is the new median?

New Median = $

Answer 1

a) $40920

b) $38500

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

`(\$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
