In a research scenario, you are testing whether a new drug is more effective than an existing one. Which hypothesis should you state as the null hypothesis (H0)?
Understand the Problem
The question is asking which hypothesis should be stated as the null hypothesis when testing if a new drug is more effective than an existing drug. It offers four options to choose from, reflecting different assumptions about the effectiveness of the new drug compared to the existing one.

The null hypothesis (H0) should state that there is no difference in effectiveness between the new drug and the existing drug.
Answer for screen readers

More Information
In hypothesis testing, the null hypothesis is typically a statement of no effect or no difference. It serves as the default or benchmark assumption.
