Naa a is 5 because all of the 11 dogs could be under 26 but all in the group 30-40 are definitely above 26

#

And ur right for b

#

So we basically don’t know how the 11 dogs are distributed in the class of 20-30

#

So they could be anywhere

#

So for the minimum number of dogs you want the least amount of dogs above 26 so we could assume that all dogs weigh 20 21…. 25 but none weight 26+

#

So then you can’t change the final interval for a minimum as they belong to a higher class, and so you count all of them
