Answer 1

Company B is better in salary then Company A.

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 :

⇒ $Mean = \frac{41000+63000}{2}$

⇒ $Mean = \frac{104000}{2}$

⇒ $Mean = 52,000$ , 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 :

⇒ $Mean = \frac{45000+65000}{2}$

⇒ $Mean = \frac{110000}{2}$

⇒ $Mean = 55,000$ , 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.
