Answer:
The standard error of the mean (SE) is of 0.326lb.
Step-by-step explanation:
The standard error of the mean is given by the following formula:
[tex]SE = \frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
In this problem, we have that:
[tex]s = 4.3, n = 174[/tex]
Then
[tex]SE = \frac{s}{\sqrt{n}} = \frac{4.3}{\sqrt{174}} = 0.326[/tex]
The standard error of the mean (SE) is of 0.326lb.
