**Study Overview:**
Jones, Thomas, and Piper (2003) conducted research to examine how alcohol influences judgments of attractiveness for the opposite sex. Male college students participated, divided into groups based on their alcohol consumption: none or moderate. They rated the attractiveness of female photographs on a 7-point scale (7 representing the highest attractiveness).
**Study Results:**
The table below presents the findings:
| Alcohol Consumption | Mean | SE |
|---------------------|------|------|
| None | 3.49 | 0.20 |
| Moderate | 4.09 | 0.22 |
**Tasks:**
a. Construct a bar graph representing the data from the table.
b. Use the graph to evaluate if alcohol consumption influences perceived attractiveness.
**Graph Explanation:**
To illustrate the data, generate a bar graph with the x-axis representing the levels of alcohol consumption ("None" and "Moderate") and the y-axis indicating the mean attractiveness rating. Each bar reflects the mean value for its category, with error bars representing the standard errors (SE) of 0.20 for "None" and 0.22 for "Moderate."
