A random sample of 38 college students had left an average tip of $5.29, with a standard deviation of $1.03. A random sample of 47 non-college-student adults had left an average tip of $6.45, with a standard deviation of $0.86. Find the test statistic (2 decimals): Give the P-value (4 decimals):

**Title: Hypothesis Testing on Tipping Habits of College Students vs. Other Adults**

**Introduction**
A pizza delivery driver recently raised a concern that college students do not tip as generously as other adults. To verify this claim, a hypothesis test was conducted at a significance level of \( \alpha = 0.10 \). In this context, \( \mu_C \) represents the average tip left by a college student, while \( \mu_0 \) symbolizes the average tip left by other adults.

**Hypotheses**
The correct hypotheses for this test are:
- Null Hypothesis (\( H_0 \)): \( \mu_C = \mu_0 \)
- Alternative Hypothesis (\( H_1 \)): \( \mu_C < \mu_0 \)

**Sample Data**
- A random sample of 38 college students left an average tip of $5.29, with a standard deviation of $1.03.
- A random sample of 47 non-college adults left an average tip of $6.45, with a standard deviation of $0.86.

**Statistical Analysis**
- **Test Statistic**: [Calculate and insert the value with 2 decimal places here]
- **P-value**: [Calculate and insert the value with 4 decimal places here]

**Results**
The analysis led to the decision to reject the Null Hypothesis.

**Conclusion**
There is significant evidence to suggest that, on average, college students tip less than their non-college-student counterparts. This conclusion might influence businesses and service providers to consider this behavior in their service strategies.

**Explanation of Visuals**
- The first diagram is a selection box showing different hypothesis options, where the correct option (indicating \( \mu_C = \mu_0 \) vs. \( \mu_C < \mu_0 \)) is marked.
- The second part contains options for test results, indicating the decision to reject the null hypothesis.
- The final section presents the conclusion options, highlighting the significant evidence suggesting the tipping difference between college students and other adults.
