Answer:
Option B) 9.1
Step-by-step explanation:
We are given the following in the question:
Average score = 490.4
Standard deviation = 63.7
Sample size, n = 49
Formula:
![=\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Putting values, we get,
Standard error =
![=\dfrac{\sigma}{\sqrt{n}} = \dfrac{63.7}{\sqrt{49}} = 9.1](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%20%5Cdfrac%7B63.7%7D%7B%5Csqrt%7B49%7D%7D%20%3D%209.1)
Thus, the correct answer is
