A food safety guideline is that the mercury in fish should be below 1 part per million (ppm). Listed below are the amounts of mercury (ppm) found in tuna sushi sampled at different stores in a major city. Construct a 98% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi? 0.56 0.80 0.10 0.97 1.34 0.56 0.90

### Mercury Levels in Tuna Sushi

**Guideline:**  
A food safety guideline states that the mercury in fish should be below 1 part per million (ppm). 

**Data:**  
Listed below are the mercury (ppm) levels found in tuna sushi sampled at different stores in a major city:

- 0.56
- 0.80
- 0.10
- 0.97
- 1.34
- 0.56
- 0.90

**Task:**  
Construct a 98% confidence interval estimate of the mean amount of mercury in the population. Determine whether there appears to be too much mercury in tuna sushi.

---

**Question:**  
What is the confidence interval estimate of the population mean \( \mu \)?

**Answer Template:**  
\[ \text{ppm} < \mu < \text{ppm} \]  
*(Round to three decimal places as needed.)*
