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

[tex]SE = \frac{s}{ \sqrt{n} }}[/tex]

where:

SE = standard error

s = standard deviation

n = the sample size

In this problem we have

[tex]s=3.40\ g\\n=35[/tex]

substitute in the formula

[tex]SE = \frac{3.40}{ \sqrt{35}}}[/tex]

[tex]SE=0.57[/tex]
