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.

Step-by-step explanation:

Definition:

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

Let 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 :

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

Hence, the set of hypothesis :

what is the graph

step-by-step explanation:
