**Study on Compression Strength of Aluminum Cans** A study examines the compression strength (in pounds) of 12-ounce aluminum cans filled with two different beverages: a strawberry drink and cola. The study aims to determine if the extra carbonation in cola results in a higher average compression strength compared to the strawberry drink. **Data Summary:** | Beverage | Sample Size | Sample Mean | Sample St. Dev. | |-----------------|-------------|-------------|------------------| | Strawberry drink| 15 | 546 | 21 | | Cola | 15 | 560 | 15 | **Analysis Questions:** 1. **P-Value Calculation:** Does the data suggest a statistically significant difference in average compression strength due to extra carbonation? Use a P-value approach with an alpha level of 0.05. 2. **Assumptions:** What assumptions are necessary for conducting this analysis? Consider assumptions of normality, independence, and equal variance. 3. **Confidence Interval Construction:** After testing, construct a 90% confidence interval for the difference in population means (Cola - Strawberry drink). This study provides insights into material strength differences influenced by beverage carbonation, crucial for packaging design and material choice.
