Question

Dang this hard, i need some help

Answer 1

Hello!

Part (A)

`\text{Mean} = \frac{\text{sum of all salaries}}{\text{number of workers}} =(13500 + 27500+13750 + 79000+ 19250 + 29000+21000)/(7) \\\\\text{Mean}= 29000 \text{ dollars}`

Part (B)

==> The mean of other six worker's salary

`\text{Mean}= \frac{\text{sum of the 6 worker's salary}}{\text{number of workers} }=(13500+27500+13750+19250+29000 + 21000)/(6) \\\\ \text{Mean}= (124000)/(6)=20,666.67 \text{ dollars}`

Hope that helps!
