A hospital director is told that 30% of the treated patients are uninsured. The director wants to test the claim that the percentage of uninsured patients is less than

the expected percentage. A sample of 340 patients found that 85 were uninsured. State the null and alternative hypotheses.

Respuesta :

Answer: [tex]H_0: p=0.30[/tex]

[tex]H_a: p <0.30[/tex]

Step-by-step explanation:

Definition:

Null Hypothesis : It is a statement about the population parameter that contains = , ≤ and ≥ signs.

Alternative hypothesis : It is also a statement about the population parameter against the null hypothesis that contains ≠  , < and > signs.

For the given situation.

Let [tex]\mu[/tex] be the population proportion of treated patients are uninsured.

A hospital director is told that 30% of the treated patients are uninsured.

Then, Null Hypothesis : [tex]H_0: p=0.30[/tex]

The director wants to test the claim that the percentage of uninsured patients is less than  the expected percentage.

i.e. Alternative hypothesis : [tex]H_a: p <0.30[/tex]

Hence, the set of hypothesis :

[tex]H_0: p=0.30[/tex]

[tex]H_a: p <0.30[/tex]
