A food safety guideline is that the mercury in fish should be below 1 part per million (ppm). Listed below are th amounts of mercury (ppm) found in tuna sushi sampled at different stores in a major city. Construct a 95% con interval estimate of the mean amount of mercury in the population. Does it appear that there is too much merc tuna sushi? 0.60 0.69 0.10 0.95 1.38 0.51 0.90 O What is the confidence interval estimate of the population mean u?

Question
**Section 7.2.19-T: Estimating Mercury Levels in Tuna Sushi**

A food safety guideline mandates that the mercury level in fish should not exceed 1 part per million (ppm). Presented below are measurements of mercury (ppm) found in samples of tuna sushi from various stores in a major city. Your task is to construct a 95% confidence interval estimate for the mean mercury content in the population. Does the data suggest that there is an excessive amount of mercury in tuna sushi?

**Mercury Levels in Samples (ppm):**

- 0.60
- 0.69
- 0.10
- 0.95
- 1.38
- 0.51
- 0.90

**Question:**

Calculate the confidence interval estimate of the population mean µ.

\[ \text{ppm} < \mu < \text{ppm} \]

*Ensure to round your answer to three decimal places.*

---

This exercise requires students to apply their understanding of statistics to real-world food safety concerns, reinforcing both the computation of confidence intervals and contextual interpretation of statistical results.
