1)
List could have other numbers also. It does not say these are the only numbers
Can't say
2)
Can't say
1) and 2) together - Can't say as there could be other numbers in the list which could change the std deviation. Without knowing the complete list we can't calculate the std deviation.

It is (E) and it's a tricky one too because one would have assumed that the numbers listed in statement one are all the numbers in each list.
