Question

The Ransin Sports Company has noted that the size of individual customer orders is normally distributed with a mean of $112 and a standard deviation of $9. If a soccer team of 11 players were to make the next batch of orders, what would be the standard error of the mean? 1.64 0.82 2.71 3.67

Answer 1

Answer: 2.71

Step-by-step explanation:

We know that the formula to calculate the standard error is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$, where $\sigma$ is the standard deviation and 'n' is the sample size.

Given : Standard deviation : $\sigma=\ 9$

Sample size : $n=11$

Then , the standard error of the mean is given by :-

$S.E.=\dfrac{9}{\sqrt{11}}=2.7136021012\approx2.71$

Hence, the standard error of the mean = 2.71
