*(Round to five decimal places as needed.)*

**d. Write a brief statement that interprets the confidence interval. Choose the correct answer below.**

- **A.** One has 99% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of Pepsi in a can.
- **B.** One has 99% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can.
- **C.** There is a 99% chance that the true value of the population mean weight of Pepsi in a can will fall between the lower bound and the upper bound.
- **D.** Approximately 99% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound.

### Statistical Analysis of Pepsi Can Weights

#### Summary Statistics
For a study on the weights of Pepsi in randomly selected cans, the summary statistics are as follows:
- Sample size (\( n \)): 36
- Sample mean (\( \bar{x} \)): 0.82412 lb
- Sample standard deviation (\( s \)): 0.00567 lb

We are using a confidence level of 99% to complete the following tasks:

#### Tasks
a. **Identify the Critical Value (\( t_{\alpha/2} \))**  
   - This value is needed to find the margin of error.
   - Round to two decimal places as necessary.

b. **Find the Margin of Error (\( E \))**  
   - Round to five decimal places as necessary.

c. **Find the Confidence Interval Estimate of \(\mu\)**  
   - Represented as \( \bar{x} - E < \mu < \bar{x} + E \)
   - Round to five decimal places as necessary.

d. **Interpret the Confidence Interval**  
   - Choose the correct statement from the options provided.
