Answer 1

A value chosen randomly from the data set will typically be contained in the interval [μ−σ,μ+σ].
A value chosen randomly from the data set will typically be contained in the interval (mu minus sigma, mu plus sigma)

Answer 2

is this right?

Answer 3

I apologize for the confusion in my response. Let me clarify:

The correct statement is:
"A value chosen randomly from the data set will typically be contained in the interval [μ−σ,μ+σ]."
