Answer:
99.7%
Step-by-step explanation:
Given that:
sample size (n) = 655
sample mean (
) = 43.29
Standard deviation
= 2.75
Let's assume we are to estimate the percentage between $33.72 and $51.54
Then;
The test statistics at 33.72 is :
![Z = \dfrac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \dfrac{33.72 -43.29}{2.75}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B33.72%20-43.29%7D%7B2.75%7D)
![Z = -3.48](https://tex.z-dn.net/?f=Z%20%3D%20-3.48)
Z at 51.54
![Z = \dfrac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \dfrac{51.54 -43.29}{2.75}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B51.54%20-43.29%7D%7B2.75%7D)
![Z = 3.00](https://tex.z-dn.net/?f=Z%20%3D%203.00)
Using the empirical standard rule, the percentage will be 99.7%
