### Analysis of Soda Can Weights

This page focuses on a hypothesis test for comparing the weights of diet soda cans to regular soda cans. Below is a detailed summary and explanation of the statistical analysis.

#### Data Summary
The table on the right in the image provides the following data:

- **Diet Soda:**
  - Sample mean (\(\bar{x}\)): 0.79971 lb
  - Sample size (n): 27
  - Standard deviation (s): 0.00434 lb

- **Regular Soda:**
  - Sample mean (\(\bar{x}\)): 0.81835 lb
  - Sample size (n): 27
  - Standard deviation (s): 0.00749 lb

#### Hypothesis Test

**Objective:**
To test if the mean weight of diet soda cans is less than the mean weight of regular soda cans using a 0.05 significance level.

**a. Hypothesis Formulation**
- Null Hypothesis (\(H_0\)): \(\mu_1 = \mu_2\)
- Alternative Hypothesis (\(H_1\)): \(\mu_1 < \mu_2\)

**Choices Provided:**
- A: \(H_0: \mu_1 = \mu_2\); \(H_1: \mu_1 < \mu_2\)
- B: \(H_0: \mu_1 = \mu_2\); \(H_1: \mu_1 \neq \mu_2\)
- C: \(H_0: \mu_1 \leq \mu_2\); \(H_1: \mu_1 > \mu_2\)
- D: \(H_0: \mu_1 \geq \mu_2\); \(H_1: \mu_1 < \mu_2\)

**Test Statistic Calculation:**
- Test statistic, \(t\), is provided (to be rounded to two decimal places as needed).

**P-value:**
- Compute the P-value (round to three decimal places as needed).

**Conclusion Statement:**
- A. Fail to reject. Insufficient evidence that diet cans weigh less than regular.
- B. Reject. Insufficient evidence for lower weight.
- C. Reject. Sufficient evidence for lower weight.
- D. Fail to reject. Insufficient evidence for lower weight.
