Question
**Clinical Trial Analysis on Flu-like Symptoms**

In a clinical trial, 20 out of 880 patients taking a prescription drug daily complained of flu-like symptoms. It is known that 1.9% of patients taking competing drugs complain of flu-like symptoms. Is there sufficient evidence to conclude that more than 1.9% of this drug’s users experience flu-like symptoms as a side effect at the α = 0.05 level of significance?

1. **Hypothesis Testing Requirements:**

   - **Criterion:** Because \( np_0 (1 - p_0) = \) [Input Field] \(\geq 10\), the sample size is [Drop-down: less than / greater than] 5% of the population size, and the sample [Drop-down: can be reasonably assumed to be random] the requirements for testing the hypothesis [Drop-down: are / are not] satisfied.

2. **Drop-down Options for Sample Validity:**

   - is given to be random,
   - cannot be reasonably assumed to be random,
   - is given to not be random,
   - can be reasonably assumed to be random.

This interactive setup allows users to engage with hypothesis testing criteria, ensuring a comprehensive understanding of statistical concepts in a clinical context.
