Step-by-step explanation:
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 :
⇒ [tex]Mean = \frac{41000+63000}{2}[/tex]
⇒ [tex]Mean = \frac{104000}{2}[/tex]
⇒ [tex]Mean = 52,000[/tex] , But mean given here is $58,000 , which differ in
⇒ [tex]58000-52000[/tex]
⇒ $[tex]6000[/tex]
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 :
⇒ [tex]Mean = \frac{45000+65000}{2}[/tex]
⇒ [tex]Mean = \frac{110000}{2}[/tex]
⇒ [tex]Mean = 55,000[/tex] , But mean given here is $56,000 , which differ in
⇒ [tex]56000-55000[/tex]
⇒ $[tex]1000[/tex]
Since, Mean of Company B differs less than actual range , than Company A . So , Company B is better in salary then Company A.
