Question

An 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.
The standard error of the sample mean is
. (Round off your answer to the nearest hundredth.)

Answer 1

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

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

$SE=0.57$
