![### Regression Analysis with Multiple Variables
A statistical program is recommended.
Consider the following data for a dependent variable \( y \) and two independent variables, \( x_1 \) and \( x_2 \):
| \( x_1 \) | \( x_2 \) | \( y \) |
|------- |------- |-----|
| 30 | 94 | 148 |
| 20 | 49 | 108 |
| 25 | 17 | 112 |
| 45 | 59 | 174 |
| 40 | 95 | 191 |
| 50 | 112 | 204 |
| 74 | 112 | 273 |
| 49 | 32 | 149 |
| 39 | 12 | 117 |
| 55 | 16 | 211 |
#### Task (a): Develop an Estimated Regression Equation for \( y \) Relating to \( x_1 \)
(Round your numerical values to one decimal place.)
\[ \hat{y} = \]
**Predict \( y \) if \( x_1 = 51 \).** (Round your answer to one decimal place.)
\[ \hat{y} = \]
#### Task (b): Develop an Estimated Regression Equation for \( y \) Relating to \( x_2 \)
(Round your numerical values to one decimal place.)
\[ \hat{y} = \]
**Predict \( y \) if \( x_2 = 16 \).** (Round your answer to one decimal place.)
\[ \hat{y} = \]
#### Task (c): Develop an Estimated Regression Equation for \( y \) Relating to \( x_1 \) and \( x_2 \)
(Round your numerical values to one decimal place.)
\[ \hat{y} = \]
**Predict \( y \) if \( x_1 = 51 \) and \( x_2 = 16 \).** (Round your answer to one decimal place.)
\[ \hat{y} = \]
**Explanation of Diagram:**
The table above consists of three columns: \( x_1 \), \( x_2 \), and \( y \). Each row represents an observation, denoting the values of the independent variables \( x_1 \) and \( x_2 \),](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F928f3826-faea-4936-b5b6-4aab28469498%2F5ef9bc33-9537-4a91-b219-2e8f63014adb%2Fi7s38hl_processed.png&w=3840&q=75)
