Consider the provided information.
Here the required claim is whether the pipe welds in a nuclear power plant meet specifications or not.
It is given that mean strength of welds should exceed 100 lb/in².
This can be written as: ![\mu>100](https://tex.z-dn.net/?f=%5Cmu%3E100)
So, the null hypothesis must be opposite of this ![\mu\leq 100](https://tex.z-dn.net/?f=%5Cmu%5Cleq%20100)
Which we can rewrite as ![\mu=100](https://tex.z-dn.net/?f=%5Cmu%3D100)
Alternative hypothesis is represent the claim, μ>100
So the null and alternative hypothesis should be
respectively.
The answer to your question is 54.28 and 23.67.
