Answer:
The standard error of the sample mean is 0.57.
Step-by-step explanation:
It is given that the experiment is set up to study the weights of 35 mice after they are injected with a drug. The population mean is 23.50 grams with a standard deviation of 3.40 grams.
[tex]n=35[/tex]
[tex]\mu=23.50[/tex]
[tex]\sigma=3.40[/tex]
The formula for standard error of the sample mean is
[tex]S.E.=\frac{\sigma}{\sqrt{n}}[/tex]
[tex]S.E.=\frac{3.40}{\sqrt{35}}[/tex]
[tex]S.E.=0.5747[/tex]
[tex]S.E.\approx 0.57[/tex]
Therefore the standard error of the sample mean is 0.57.
