rjkz [21]

Answer:

<h2>The standard error of the mean is 7.56</h2>

Step-by-step explanation:

The standard error of the mean is defined as the ratio of standard deviation to the square root of the sample size of a data. The standard error of the mean is mathematically expressed as shown below;

X = \frac{\sigma}{\sqrt{n} }

X is the standard error of the mean

\sigma is the standard deviation

n is the sample size.

Given;

\sigma = 121\\n = 256

On substitution into the formula we have;

X = \frac{121}{\sqrt{256} }

X = \frac{121}{16} }\\

X ≈ 7.56
