Answer:
Five plus the difference of seventeen and eight
Answer:
-3.2 is the smallest integer
Step-by-step explanation:
Considering the situation described, the hypothesis tested are given as follows:
- The null hypothesis is
![H_0: \sigma \geq 23](https://tex.z-dn.net/?f=H_0%3A%20%5Csigma%20%5Cgeq%2023)
- The alternative hypothesis is
![H_1: \sigma < 23](https://tex.z-dn.net/?f=H_1%3A%20%5Csigma%20%3C%2023)
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:
![H_0: \sigma \geq 23](https://tex.z-dn.net/?f=H_0%3A%20%5Csigma%20%5Cgeq%2023)
At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:
![H_1: \sigma < 23](https://tex.z-dn.net/?f=H_1%3A%20%5Csigma%20%3C%2023)

Step-by-step explanation:
![= 4 + ( - 3) - 2 ( - 6)](https://tex.z-dn.net/?f=%20%3D%204%20%2B%20%28%20-%203%29%20-%202%20%28%20-%20%206%29)
here ( + ) × ( - ) = ( - )
![= 4 - 3 + 12](https://tex.z-dn.net/?f=%20%3D%204%20-%203%20%2B%2012)
![= 4 + 12 - 3](https://tex.z-dn.net/?f=%20%3D%204%20%2B%2012%20-%203)
![= 16 - 3](https://tex.z-dn.net/?f=%20%3D%2016%20-%203)
![= 13](https://tex.z-dn.net/?f=%20%3D%2013)
