Transcribed Image Text:**Financial Performance Data Table**
This table provides key financial metrics across various records. The columns are defined as follows:
- **ROAA (%)**: Return on Average Assets, a measure of a company's profitability relative to its total assets.
- **Efficiency Ratio (%)**: Indicates the expenses as a percentage of revenue, used to gauge efficiency.
- **Total Risk-Based Capital (%)**: A measure of a bank's capital, considering the riskiness of assets in its balance sheet.
**Data:**
| ROAA (%) | Efficiency Ratio (%) | Total Risk-Based Capital (%) |

![**Regression Analysis of Bank Profitability**
Profitability remains a challenge for banks and thrifts with less than $2 billion of assets. One of the critical business problems for bank analysts is understanding the factors that affect the return on average assets (ROAA), which indicates how profitable a company is relative to its total assets.
In this scenario, data collected from a sample of 20 community banks resulted in the regression model:
\[
\hat{Y}_i = -4.511 + 0.037X_{1i} + 0.217X_{2i}
\]
where \(Y\) is the ROAA (%), \(X_1\) is the efficiency ratio (%), and \(X_2\) is the total risk-based capital (%).
### Objective
Complete parts (a) through (d) below.
- **a. Plot the Residuals versus \(\hat{Y}_i\):**
The task is to choose the correct graph that plots the residuals against the predicted values (\(\hat{Y}_i\)).
### Graphs:
Below are four potential graphs labeled A, B, C, and D, where the x-axis represents "Predicted Y" and the y-axis represents "Residuals."
- **Graph A:** The residuals are mostly uniform across different predicted values, indicating a random distribution.
- **Graph B:** Residuals appear to have a pattern, clustering in certain areas, suggesting possible issues with the regression model's assumptions.
- **Graph C:** The residuals are scattered randomly without a discernible pattern, which is ideal for regression diagnostics.
- **Graph D:** The residuals demonstrate a systematic pattern, which may indicate model issues.
Choose the graph that best represents a random distribution of residuals, which typically indicates a well-fitting regression model.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc91d435c-8a20-4fa9-b80f-5aaeb9e13244%2F7f1c57fd-d0ed-481e-afd1-caf9910293bb%2Ffaen9ri_processed.png&w=3840&q=75)
