**coefficient of variance ????**

ok i know that coefficient of variance is calculated using the equation

CV=(standard deviation /mean value)*100...

here is my problem ..Two TV manufacturing companies have provided the mean values and SD of the life time of their TVs .after calculating for one company i got CV as 18.7% and for other i got 16.9%.so i just want to know can i get a idea of what is the better company by looking@ this CV .if so how r u going approach ur answer ?i want reasons for that!.....waiting for help ..thanks you!

(im giving mean and SD values here if u want them in ur argument but i think CV is sufficient ......for first mean =1495Hrs SD=280Hrs........for second mean=1875Hrs and SD=310Hrs)
