A hospital director is told that 31 % of the emergency room visitors are uninsured. The director wants to test the claim that the percentage of uninsured patients is less than the expected percentage. A sample of 300 patients found that 75 were uninsured. State the null and alternative hypotheses.
Let's define the null and alternative hypotheses for the given situation:
Null Hypothesis (H0): The percentage of uninsured patients in the emergency room is equal to or greater than the expected percentage (31% or more).
Alternative Hypothesis (Ha): The percentage of uninsured patients in the emergency room is less than the expected percentage (less than 31%).
Mathematically, we can represent the hypotheses as follows:
H0: p ≥ 0.31 (where p is the population proportion of uninsured patients) Ha: p < 0.31
In words, the null hypothesis states that the percentage of uninsured patients is 31% or higher, while the alternative hypothesis states that the percentage of uninsured patients is less than 31%. The hospital director wants to test if there is enough evidence to support the claim that the percentage of uninsured patients is less than expected.
