**Hypothesis Testing on Tamiflu and Nausea as a Side Effect**

You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. This is because nausea is common for people who have the flu. From past studies, you know that about 34% of people who get the flu experience nausea. You collected data on 2248 patients who were taking Tamiflu to relieve symptoms of the flu, and found that 828 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symptoms and experience nausea is greater than 34%.

**a) Identify the null and alternative hypotheses:**

**Null Hypothesis (H0):** ?  
**Alternative Hypothesis (Ha):** ?  

**b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?**

- Left-tailed
- Right-tailed
- Two-tailed

**c) Identify the appropriate significance level:**

**Significance Level:**   

**d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places:**

**Test Statistic:**   

**e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places:**

**p-value:**  

**f) Do you reject the null hypothesis?**

- We reject the null hypothesis, since the p-value is less than the significance level.
- We reject the null hypothesis, since the p-value is not less than the significance level.
- We fail to reject the null hypothesis, since the p-value is less than the significance level.
- We fail to reject the null hypothesis, since the p-value is not less than the significance level.

**g) Select the statement below that best represents the conclusion that can be made:**

- There is sufficient evidence to warrant rejection of the claim that the percentage of people who experience nausea is greater than 34%.
- There is not sufficient evidence to warrant rejection of the claim that the percentage of people who experience nausea is greater than 34%.
- The sample data support the claim that the percentage of people who experience nausea is greater than 34%.
- There is not sufficient sample evidence to support the claim that the percentage
