Answer:
The null hypothesis is [tex]H_0: \mu = 23.2[/tex]
The alternate hypothesis is [tex]H_a: \mu \neq 23.2[/tex]
Step-by-step explanation:
Null hypothesis:
The product is supposed to contain 23.2% potassium by weight, which means that at the null hypothesis, we test that this is the correct weight. So
[tex]H_0: \mu = 23.2[/tex]
Alternate hypothesis:
If the mean percentage is found to differ from 23.2, the manufacturing process will be recalibrated, which means that we test if the mean differs from 23.2, that is:
[tex]H_a: \mu \neq 23.2[/tex]
