Hello guys , I need your help , to elaborate I included the table below 

I have gategories ( Mobile-TV-Watches) that has average shipping delay per day , 

but in fact it is not correct for me , because for example in mobile category Samsung delay is 10 days, Apple is 15 , and nokia is 10 days , but in Average shipping culumn it gives me the sum of the average 35, and not the max which should be 15

how to solve this issue 

thanks in advance

category	Quantity	Average shipping delay per days
mobile	4	35
TV	3	64
Watches	4	33
