Idon't know how to do 6 and 7 and also i don't understand why

I don't really understand either but here is what I think:

1=m, 2=n, ect.

So what x and y could be:

X=12
Y=13

Im not sure but those are my answers. Hope it somehow helps!!

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
