    Answer:

    The standard error of the sample mean is 0.57

    Step-by-step explanation:

    we know that

    The Standard Error Formula is  given by the formula

    SE =  \frac{s}{ \sqrt{n} }}

    where:

    SE = standard error

    s = standard deviation

    n = the sample size

    In this problem we have

    s=3.40\ g\\n=35

    substitute in the formula

    SE =  \frac{3.40}{ \sqrt{35}}}

    SE=0.57
