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 99% confiden interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi? 0.51 0.71 0.10 0.87 1.27 0.54 0.85 What is the confidence interval estimate of the population mean μ? ppm <μ

### Mercury Levels in Tuna Sushi: Food Safety Analysis #### Introduction A food safety guideline states that the mercury level in fish should be below 1 part per million (ppm). Below are the observed amounts of mercury (ppm) found in tuna sushi samples collected from various stores in a major city. To assess the safety of these samples, we will construct a 99% confidence interval estimate for the mean amount of mercury in the population. This will help determine if the mercury levels in tuna sushi are within safe limits. #### Mercury Levels Observed in Tuna Sushi Samples - 0.51 ppm - 0.71 ppm - 0.10 ppm - 0.87 ppm - 1.27 ppm - 0.54 ppm - 0.85 ppm #### Confidence Interval Estimate We are required to calculate the confidence interval estimate of the population mean (μ) for mercury levels in tuna sushi samples. **Question:** What is the confidence interval estimate of the population mean μ? **Select the appropriate values to complete the interval:** \[ \Box \text{ ppm } < \mu < \Box \text{ ppm } \] *(Round to three decimal places as needed.)* #### Analysis This analysis will determine whether the mean mercury level is below the safety guideline of 1 ppm. If the upper bound of the 99% confidence interval is below 1 ppm, it suggests that there is not too much mercury in tuna sushi. However, if the upper bound exceeds 1 ppm, further investigation and potential measures may be required to ensure food safety.
