![**Eat your cereal:**
Boxes of cereal are labeled as containing 14 ounces. The following are the weights, in ounces, of a sample of 16 boxes. It is reasonable to assume that the population is approximately normal.
Weights:
- 14.07, 13.99, 14.16, 14.17, 14.15, 14.07, 14.13, 13.99
- 14.03, 14.02, 14.09, 14.10, 14.20, 14.18, 14.04, 14.03

Construct a 98% confidence interval for the mean weight. Round the answers to three decimal places.
\[ \square \ < \mu < \ \square \]

**Part: 1 / 2**
**Part 2 of 2**
The quality control manager is concerned that the mean weight is actually less than 14 ounces. Based on the confidence interval, is there a reason to be concerned?
The quality control manager should (Choose one) ▼ concerned that the mean weight is actually less than 14 ounces.
\[ \text{Dropdown options include: (be, not be)} \]
---
**Graph or Diagram Explanation:**
This exercise involves calculating a confidence interval and assessing whether the mean weight of cereal boxes is below the labeled 14 ounces. The progress is visually represented in two parts, with the first part involving the calculation of the confidence interval and the second part involving a decision-making process based on the calculated interval.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F231fae22-ac62-4382-9eb0-95d912af77d1%2F29e6071c-4100-4cf5-8798-2f79ecc04e73%2Frn2od2a_processed.png&w=3840&q=75)
