![**Problem Statement:**
A manager wishes to determine the relationship between the number of miles (in hundreds of miles) the manager's sales representatives travel per month and the amount of sales (in thousands of dollars) per month. Find the standard error of estimate, \( S_e \), given that:
\[ \hat{y} = 3.428x + 39.547 \]
**Data Table:**
| Miles Traveled, \( x \) | 6 | 3 | 12 | 2 | 7 | 5 | 11 | 13 | 9 |
|--------------------------|---|---|----|---|---|---|----|----|---|
| Sales, \( y \) | 62| 51| 79 | 44| 67| 54| 80 | 82 | 70|
**Summations:**
\[
\sum x = 68 ; \quad \sum y = 589
\]
\[
\sum x^2 = 638 ; \quad \sum y^2 = 40051
\]
\[
\sum xy = 4876
\]
**Options for Standard Error of Estimate, \( S_e \):**
A. \( S_e = 1.613 \)
B. \( S_e = 2.845 \)
C. \( S_e = 4.765 \)
D. \( S_e = 2.475 \)
E. \( S_e = 6.127 \)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa39be845-ae1d-44f6-957a-0c42c0fe4c23%2F8e341d90-608a-43a5-a5d2-d31ddfface8c%2F700ba9l_processed.jpeg&w=3840&q=75)
