Your medical research team is investigating the mean cost of a 30-day supply of a certain heart medication. A pharmaceutical company thinks that the mean cost is more than $64. You want to support this claim. How would you write the null and alternative hypotheses?
H₀ [Dropdown]
Hₐ [Dropdown]
**Explanation:**
The image presents a scenario for a hypothesis testing problem. The task is to write the null hypothesis (H₀) and the alternative hypothesis (Hₐ) to evaluate a claim about the mean cost of a 30-day supply of a heart medication. The claim suggested by a pharmaceutical company is that the mean cost is more than $64.
- The **null hypothesis (H₀)** typically states that there is no effect or no difference. In this context, it would suggest that the mean cost is less than or equal to $64.
- The **alternative hypothesis (Hₐ)** is what you want to support, indicating that the mean cost is greater than $64.
The dropdown options would likely allow you to select inequality signs or complete statements to form these hypotheses.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6df99eeb-1241-43a9-ba5e-1087d9c508bc%2Fc4bbd964-620f-418b-a4a0-365177b31848%2Ffh0r1i_processed.jpeg&w=3840&q=75)
