So , for firm 1 ,

the Range = 74 ± 4

= 74 + 4       and      74 - 4

= 78     and   70

the range for firm 2 is

= 72 ± 5.1

= 72 + 5.1      and      72 - 5.1

= 7.1        and       66.9  

The second company has a lower range and it should be preferred .

Therefore ,  The best firm for the Appliance manufacturer for the repair work is Firm 2 .
