Here we have , The annual salary for a computer technician at Company A ranges from $41,000 to $63,000, with a mean of $58,000. At Company B, the annual salary for the same position ranges from $45,000 to $$65,000, with a mean of $56,000. We need to find BEST compares the salaries of computer technicians for the two companies . Let's find out:

The annual salary for a computer technician at Company A ranges from $41,000 to $63,000, with a mean of $58,000 , So Mean :

⇒
`Mean = (41000+63000)/(2)`

⇒
`Mean = (104000)/(2)`

⇒
`Mean = 52,000` , But mean given here is $58,000 , which differ in

⇒
`58000-52000`

⇒ $
`6000`

The annual salary for a computer technician at Company A ranges from $45,000 to $65,000, with a mean of $56,000 , So Mean :

⇒
`Mean = (45000+65000)/(2)`

⇒
`Mean = (110000)/(2)`

⇒
`Mean = 55,000` , But mean given here is $56,000 , which differ in

⇒
`56000-55000`

⇒ $
`1000`

Since, Mean of Company B differs less than actual range , than Company A . So , Company B is better in salary then Company A.
