Hi! Wanted to clarify a doubt here-
Here, we have not considered the case of a case with same numbers because the question specifies this is a “set” and repeats are not allowed in a set?
The question specifies that ‘b’ is not equal to 0.
(‘b’ being the Standard Deviation)
If we consider a set of same numbers, let’s say: 2, 2, 2, 2, 2
Then the mean ‘a’ = 2 and the standard deviation ‘b’ would be = 0
(which contradicts the question)
Hence, we cannot consider this case.
Aah! Understood, thank you for clarifying this
