    Answer: The standard error for sample is 0.0686 .

    Step-by-step explanation:

    We know that the formula to find the standard error is given by :-

    S.E.=\dfrac{s}{\sqrt{n}}

    , where s = standard deviation

    n= Sample size

    As per given , we have

    s=  $0.4  and n= 34

    Then , the standard error for sample is given by :-

    S.E.=\dfrac{0.4}{\sqrt{34}}=\dfrac{0.4}{5.83095189485}\\\\=0.0685994340569\approx0.0686

    Hence , the standard error for sample is 0.0686 .
