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

Explanation:

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

`S.E.=(\sigma)/(√(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.=(9)/(√(11))=2.7136021012\approx2.71`

Hence, the standard error of the mean = 2.71
