![Is a statistics class' delivery type a factor in how well students do on the final exam? The table below shows the average percent on final exams from several randomly selected classes that used the different delivery types.
| | Face-to-Face | Hybrid | Online |
|-----|--------------|--------|--------|
| 1 | 63 | 78 | 87 |
| 2 | 78 | 62 | 63 |
| 3 | 89 | 99 | 97 |
| 4 | 79 | 71 | 64 |

Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of \( \alpha = 0.1 \).
**Hypotheses:**
- \( H_0: \mu_1 = \mu_2 = \mu_3 \)
- \( H_1: \) At least two of the means differ from each other.
**Steps:**
1. For this study, we should use [Select an answer].
2. The test-statistic for this data = [ ] (Please show your answer to 3 decimal places.)
3. The p-value for this sample = [ ] (Please show your answer to 4 decimal places.)
4. The p-value is [Select an answer] \( \alpha \)
5. Based on this, we should [Select an answer] hypothesis.
6. As such, the final conclusion is that...
- There is sufficient evidence to support the claim that course delivery type is a factor in final exam score.
- There is insufficient evidence to support the claim that course delivery type is a factor in final exam score.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4726056b-a0d8-4167-a534-8f03670a441a%2F3c219b42-7a78-49a6-8917-8a89fd506953%2Fm0si4y4_processed.png&w=3840&q=75)
