A certain statistics instructor participates in triathlons. The accompanying table lists times (in minutes and seconds) he recorded while riding a bicycle for five laps through each mile of a 3-mile loop.

**Hypothesis Testing of Triathlon Riding Times**

**Objective:**
To determine if all three miles in a triathlon loop have the same mean riding time, using a 0.05 significance level, indicating if any of the miles might have a hill affecting the riding time.

**Riding Time Data:**
For each mile, the times for five laps are recorded in minutes and seconds.

- **Mile 1:** 3:16, 3:23, 3:21, 3:23, 3:21
- **Mile 2:** 3:19, 3:22, 3:22, 3:16, 3:20
- **Mile 3:** 3:33, 3:31, 3:28, 3:30, 3:28

(Note: When using this data, convert each time into total seconds for analysis.)

**Hypothesis Setup:**
- **Null Hypothesis (H₀):** All three miles have the same mean riding time.
- **Alternative Hypothesis (H₁):** At least one mile has a different mean riding time.

**Analysis Method:**
- Compute the F test statistic. (Formula and computation required)
- Find the P-value associated with the F test statistic.

**Conclusion Criteria:**
- **Fail to Reject H₀:** Insufficient evidence to claim a difference in mean times.
- **Reject H₀:** Sufficient evidence that mean times differ among the miles.

**Conclusion Options:**
- **A. Fail to reject H₀** – The three different miles have the same mean ride time.
- **B. Reject H₀** – The three different miles do not have the same mean ride time.

**Hill Analysis:**
Determine if any mile appears to take longer, potentially due to a hill:
- **A. Mile 1 appears longer - possible hill**
- **B. Mile 2 appears longer - possible hill**
- **C. Mile 3 appears longer - possible hill**
- **D. No mile appears longer**
- **E. Both Mile 1 and Mile 3 appear longer - possible hills**

Use this analysis framework to evaluate the provided data and draw conclusions regarding the riding times and the potential presence of hills along the course.
